Z77A GD65 - Samsung Green Memory Issue

Hi all,
I have just built my new Ivy Bridge Machine:
MSI Z77A GD65 (BIOS V10.5)
i5 3570K
16GB Samsung Green Memory DDR3 PC3-12800 30nm (4x4GB)
There has been a lot of forum chatter regarding the Samsung Green memory and its incredible overclocking potential. Unfortunately the MSI Z77A GD65 fails to POST at anything above the default 1600MHz. I have tried different RAM timings and increasing the voltage to 1.65V, but nothing got my system to POST.
After doing some forum digging I discovered I am not alone, with other GD65 users having exactly the same problem.
As a result this feels like a BIOS issue with V10.5. Can anyone help?
Cheers,
Matt.

To OC that RAM higher than 1600 makes virtually no difference to your real performance but adds a lot of potential instabilities. CPU OC yields the real performance gains.
With a Sandy Bridge CPU... I would agree with you.
This is most definitely not the case with Ivy! There are noticeable real-world improvements - if there weren't, I wouldn't be so fussed.
Gigabyte have recognised the similar (same) issue they're suffering with Z77 boards... it's now been a month since anyone replied to me on this issue.
Asus/ASRock do not have this issue - so it's not related to Z77 or the RAM.

Z77A-GD65 Intermittent Power Up Issue

Ever since I've had this board, it's been problomatic getting it to start at times. Most of the time it starts just fine, other times the fans just barely spin and it fails to start. Repeatedly pressing the start button usually gets it going after maybe a dozen rapid pressings (think Morse Code).
I've tried jumping the pins on the header on the board, no difference. I've tried pressing the power button on the board, no difference.
Sometimes, however, repeatedly pressing the power button does not get it to start. These times I have to disconnect the power cord and wait for the power button on the board to go out, usually takes 30 seconds or so for the board to totally discharge. Now it will power up right away, I have the BIOS set to power up after a power loss.
Of course I've tried the usual things like one stick of RAM only in Slot 2, different sticks of RAM, only one GPU, no GPU, check for shorts to the case, properly seated CPU, etc. But as it is an intermittent issue, it'll seem fine for a while then go right back to not starting, then start right up the next time without any issues. It will always start with a CLEAR CMOS, but that is not a very handy method of booting the computer.
The system is very stable after it is running, which leads me to think the individual components are not faulty. It never has any problem establishing a restart, only a cold boot. The HEX readout is always A0 when it's running, it's never had any problem booting up after it establishes power.

What is the ME version in bios?
If you remove the OC does the problem go away?
I'm at work right now, not sure about the ME version. Can you elaborate what that is?
OC has no effect, it's been doing this since long before I even attempted to OC anything. It's a fairly random issue. I could, for example, take the OC out and maybe it'd boot issue free for a number of tries, I'd think the issue was resolved. Then, without changing anything, it'll go back to doing it. I had this happen when I read that RAM slot 2 was determined to be the primary slot. I loaded one stick of RAM into slot 2 and got several clean starts. I was convinced I had resolved the issue, only to have it fail on the next attempt.
One thing, time appears to be an issue. I can play around with it in the evening, make multiple cold boots no problem. Then it won't start up in the morning. Or maybe it will start up in the morning, but not at lunch. Or not in the evening. But if it's just a couple or a few minutes, it'll start. And restart.

Z77A-GD65 SATA Hot Swap Issue

Hi folks, hoping someone can help with this.
I have attached a 2-port rear eSATA bracket to my Z77A-GD65. When I connect and power up an external drive to either of these ports, W7 recognises the drive just fine, but it does not appear in the "safely remove hardware" menu, nor is it ejectable by right-clicking the drive's icon in Windows Explorer.
I initially connected the bracket to chipset SATA ports 4 & 6, with the "hot plug" feature for these ports set to "enabled".
Intel Rapid Storage drivers are installed and the main system drive is RAID0 (2x256GB SSDs) in 6GB/s SATA ports 1 & 2.
What I have tried so far:
- Update the motherboard BIOS (v10.0 to v10.5)
- Disable write caching on the drive in question
- Use a different drive (in an eSATA caddy)
- Connect the bracket to the ASmedia controller (SATA ports 7 & 8) in AHCI mode, instead of the Intel controller
So far nothing has made the drives show up in the "safely remove hardware" menu.
Any ideas?

For anyone interested, I found the solution.
Connect and power on external HD
Go to my computer
Right-click the external HD icon
Click properties
Select "Hardware" tab
Click on the entry for your external HD
Click properties
If not logged in as admin, there is a button in the "General" tab that says "Change Settings" - click it and and dismiss any UAC message
Go to the "Policies" tab
Select "Quick removal" option
Drive now appears in "safely remove hardware" menu and is ejectable from Explorer right click etc.

Z77A-GD65-Gaming Killer LAN issues

I just changed my motherboard to one that has the Qualcomm Killer E2200 chipset. However, with my existing Gigabit network (RT-N66U), I am only getting speeds of 100Mbps.
I have checked all relevant settings, reinstalled drivers, etc., even tried a Ubuntu Live CD, but the speed I'm always getting is 100Mbps.
I have tried 3 CAT5e cables including those short ones but I still can't get Gigabit speeds... I even purchased 2 CAT6 and CAT6e cables thinking it may solve the problem, but no.
The cables work fine at Gigabit speed from my laptop.
This is especially troubling for me since I have a NAS and now my speeds are only 10MB/s :(
Any idea what could be wrong? I have already tried the troubleshooting thread and removed the suite, etc. etc.

Here's a summary of what I've done (though they are all unsuccessful):
- Removed my sound card and graphics card just in case
- Installed a fresh copy of Windows 8.1 on another partition to rule out any driver issues
- Installed just the INF without the driver suite on this fresh copy
- Tried CAT6a, CAT6, and CAT5e cables of various lengths
- Tried different BIOS versions
- Tried to clean the contacts on the LAN port by using a cotton bud and small amt of alcohol (of course, the computer was turned off and the port was dried before I turned it on again)
I noticed two things:
- When I plug one end to my RT-N66U router and the other to the onboard LAN, no light lights up for about 10s. Then, the green (100mbps) LED lights and the orange (activity) LED blinks.
- When I plug one end to my Samsung Series 5 laptop and the other to the onboard LAN, the red (1Gbps) LED lights up for a split second. Windows shows that a network cable is connected. Then, after the split second it will disconnect and there will be no more lights. After ten seconds, the green (100mbps) LED lights up instead together with the blinking orange (activity) LED.
When I plug my Series 5 laptop to the router, or the Series 5 laptop to my dad's laptop, 1Gbps works fine.

Z77A-GD65 + Samsung 840 Pro Slow Windows 8.1 Boot time?

Hey guys,
I've recently installed Windows 8.1 in UEFI mode on my new Samsung 840 Pro drive.
However, just for fun I started testing my boot time.
From the moment I press the Power button I'm in Windows after 25 seconds, it seems to hang on the A2 code for about 6-8 seconds every time, however, not on restart.
A restart is much faster and only takes about 10-12 seconds.
However, I was looking in Youtube and most guys there boot their PC with inferior SSDs than mine in about 15-18 tops.
I was just wondering if a 25 seconds boot time for the fastest SSD today is considered normal?
Also, is it related to my CPU? I'm using a 2500K, I assume most of the videos I saw were of people with Ivy/Haswell bridge CPUs.
In my BIOS I am using the Windows 8 features and "Fast Boot" is enabled, "Secure Boot" is disabled.
Thanks
EDIT
Found the issue! Turns out my new WD 3TB Caviar Black drive is causing the hang. I disconnected it and my PC booted within 12 seconds since I pressed the power button.
I have the 3TB drive connected to a SATA3 port on my Intel controller.
Any thoughts?

I had this same problem with trying to install Windows 8.1 from the ISO I was able to download from MS. I eventually got the installer to work. Two ways to do this.
1. Set your BIOS boot option to Legacy + UEFI
2. Change your boot device to the legacy form of your USB flash drive
That should make it boot.
or
1. While at the shell command prompt
2. Shell> Fs0:
3. fs0:> \EFI\BOOT\BOOTX64.EFI
Or type whatever the Flash device is labeled as
Hope this helps,
I have the Z87-GD65 mobo but I imagine the Z77 has a similar bios...

https://forum-en.msi.com/index.php?topic=160781.0

Sorry, didn't realise it wasn't preferred to keep feedback over a similar issue in the same thread.
I seem to have solved this now at this 4.4GHz OC by slackening the memory timings to 11-11-11-24 Command Rate set to Auto and 1.565v DRAM Voltage.
Still appears to be a problem though when raising the OC to 4.7GHz as fails Prime 95 blend testing even with the RAM set to auto settings (1600MHz), whereas the CPU appears stable according to Prime 95 small ffs.

Re: Z77A-GD65 Intermittent Power Up Issue

Hey JRAuger,
I have the exact same problem as you: I have the same motherboard and the same BIOS version (although I had the same problem before updating, and nothing is overclocked). I RMA:ed my first motherboard and received a new one from my supplier, but the problem persists. I've bought a new PSU and tried replacing every component with ones I know for a fact are 100% OK.
The computer still boot loops. Once (and if) I somehow manage to get it to POST, the system is as stable as could be. I've successfully run Prime95 and Memtest86 for hours without reboots or errors. Once the computer has successfully started it will an can both shut down and restart without any problems. However, it seems if I leave the computer off for a couple of hours, the problem reappears. I have no idea what's going on but it's starting to get quite irritating.
I've already breadboarded the computer once to rule out short-circuits caused by the chassis. To me, it sounds like a BIOS update provided by MSI is in order...

(Same board btw)
I too had this problem after I installed my custom WC loop. My PC would boot up for 5 seconds or so and then shut down and cycle this process. I moved my ram in all the slots and it didn't work and someone hinted that I try only 1 stick of ram. Well sure enough 1 stick of ram in DRAM1 booted the PC up just fine. I switched that stick for my other one, (2x4GB Mushkin 1333MHz Blackline) and it too worked fine. So as far as I know my ram sticks are good. Now mind you when I first got this PC months ago and built it both ram sticks and slots works in sync of each other just fine. After sitting torn apart for a few weeks as I was case modding, etc, the system started boot cycling. I've come to the conclusion that both ram sticks are good but that my board doesn't or stopped support dual ram. If I had more ram I would try it with all 4 slots but I only have the 2 sticks.
When I boot with 1 stick I get post code A0.
When I boot with 2 sticks in I get post code error 55. (Early Memory Initialization) *Not sure what they mean*
I've tried CMOS reset, I have taken the battery out of the board and jumped the JP1 or w/e pins. I am about to flash bios and see about updated but now my windows is barfing so I have to reinstall that too. Grr!!!
So!
1. Try your ram with just one stick in slot DRIMM-1
2. Call MSI and see about a replacement as I think your board may be bad too.

Z77a-gd65-new build- od issue

So I am having currently an on-going issue that is frustrating me, when I boot from off condition, it will go through it routine of checking everything than it pops up "reboot and select proper boot device" I have so far done this
Check to ensure board isn't grounded at case,
Check settings- boot option 1 is set to intel volume 1 (raided hdd's) option 2 is the asus dvd-rom all others are disabled. No fast boot
Check all cables etc
bios is 10.11 and it came shipped with that bios
Now when I enter bios and tell it to save and reboot it loads windows fine, but not from being completely off
It does recognize the raided volumes it just doesn't decide to load it ?
Ram is set correctly. I have went over again and again the setting but I don't get it.
OS is windows 7 pro
any ideas would be greatly appreciated , when it does get to window I have no issues what-so-ever it runs fast stable, I can play BF4 while oc'd to 4.1 on ultra @60-70 FPS it just is the boot up IDK, sure I can hit f11 all the time and select it there but its not suppose to be that way.
Anyway thanks in advance

No, it doesn't. Froggy just chose the wrong board by accident.
That's the right one: https://forum-en.msi.com/index.php?topic=163874.msg1279183#msg1279183
So..... I need to flash update the bios even though I'm using 10.11? Wow thanks Msi for telling me I was already using the current and correct bios.
You flobelix, I will see about doing that, it will fix a lot of unnecessary stress

It only does this in sli......Right now I have only one card in and i took the other card out...so far no issues......I just can not figure it out..
I tried a new sli brindge and that did not work....Than I switched power supply to 850 from a 750 and that did not work....each 6 pin has it own power rail..nothing brindged on the cable.....Is there a setting In bios I am missing............
Help me out guys....I am at a loss..I really want to run 2 cards.....will be testing the single card for a few more hours and that I will swap it out with the other.....But am I missing something.....Voltage on each card is kind of weird I guess..1.00 volts to .850........

Quote
I know this is besides the point...But you learn something new everyday.....so far no crash....Only difference---I have 2 sticks of ram and not 4....I really would like to know more about this. as of right now. I want to just leave the 2 sticks and make 100% sure the cards are not the issue. You would figure with this set up...I should not have any issues like that what so ever......so why would the i7 3770k have issue like this? Is it know to have problems like that? I even spent the extra cash on this build....now I am second guessing my choice. should have stuck with the z77a-gd55 or lower. So you think the cpu was having issue with the IMC and bandwidth...Talk about weird....I will keep testing like it is right now and than tmr-try uping the voltage & I/O.....I need to make 100% sure its not my cards...
I think you mis-understood (as i wasn't clear)
Set the voltage to 1.65 & 1.1 and install all 4 sticks and re-test.
I wasn't saying the cpu was broken or anything like that. What I was getting at was that the Integrated Memory Controller on dual channel machines sometime have a bit of trouble with all of the band width when hooked up to quad channel. Can also be cause by the memory itself as Froggy was saying:
Quote
Test the other two sticks individually in the primary DIMM slot to see if one or both are faulty.
Virtu-MVP was an exciting idea that hasn't really worked as well as it should due to a lack of support from LUCID. I disabled mine long ago due to nusiance issues.
Quote
Right now---since I have taken out the 2 extra sticks of Ram.....I have not had a single crash..."2 hours".I even turn up the stick to the suggested 1600...Running great...I am a firm believer if it an't broke.....Leave it alone>>>>>>>>>>LOL!!!!!I like the way it is running....
If this is the case, you can reset the dramv and I/o voltage to "Auto".
Perhaps even enable the XMP profile of the ram.

Z77A-GD65 / Video issues

Hey All
Got a real weird issue going on
Randomly when playing games my computer will shutdown and reboot. When it boots up the video card is blurry during Post and bios splash screen. Once windows attempts to load the computer reboots again.
Changing to the onboard video card works fine
If I swap the PCI-E to another slot it will work again but the issue will reoccur in a matter of time - can be days or minutes
Video Card runs in high load environments such as ARMA3 and Starcraft with issues. Previously had not experienced an issue.
It's just really weird
System
MB: MSI Z77A-GD65
Video: GTX 580
Memory: 16GB Gskill 2400
Any help or ideas would be awesome
Regards,
Mag

could be overheating for sure so like dude said check the temps under load and see if its temp is very high?
also it could be RAM errors so try >>Memtest86<< and see if it throws errors or if the computer restarts while its active?
could also be PSU related as you have not listed what power supply you have as it may be having a power shutdown issue as the PSU is not capable of sustaining a stable power delivery?

Z77A-GD65 issues with Geforce GTX 780 Video Card

Hey Guys,
I have a issue with a new PC build.
I think it may be a driver or BIOS setting issue, I hope
I bought a MSI Z77A-GD65 motherboard and below are the specs:
- Intel Core i7-2600 CPU 3.4 Ghz
- BIOS Version E4451IMS V10.8
- Balistix Sport 8GB sticks (Total of 24 GB memory installed)
- Kentek 875w power supply
- Geforce GTX 780 Graphics Card
My problem is with the Geforce GTX 780 video card, I installed a fresh install of Windows 7 64 bit and
everything runs and works fine,but when i install the Geforce GTX 780 video card and install the
drivers its all good up to this point but when i restart the computer i get this message in the device
manager ""Windows has stopped this device because it has reported problems (code 43)"
I have installed different versions of the driver, a few older and few newer versions with the same
outcome.
I tried to flash the BIOS to the latest version 10.11 but had problems with it picking up my harddrive
after it flashed successfully. I even checked the boot up setting and it all looked good just would not
boot up, so i had to revert back to the v10.8 BIOS version for it to work.
I'm not sure if there is a setting in the BIOS that i need to turn on or off. I'm not familar with this BIOS,
is there a place in it so i can see if the BIOS is picking up the video card, it has to or Windows would
not see it right?
I'm stumped here, do you guys know of a Geforce driver version that works well with this video card?
I truely think the card is fine because when i install the card to the motherboard i dont get any weird
issues until the driver is installed and Windows is restarted.
I would greatly appreciate any help and advise that you guys can give me.
Thanks alot

UPDATE
Well i wanted to post an update on my new build issue.
Here are my specs:
I bought a MSI Z77A-GD65 motherboard with BIOS v10.8
- Intel Core i7-2600 CPU 3.4 Ghz
- BIOS Version E4451IMS V10.8 (i had a issue with the newest BIOS flash v10.11 it wouldn't detect the harddrive, could figure that one out so i went back to v10.8)
- Balistix Sport 8GB sticks (Total of 32 GB memory installed) I first had 3 sticks so i got another 8GB stick to fill all 4 banks for total of 32 GB
- Corsair Professional Series 860 Watt Digital ATX/EPS Modular 80 PLUS Platinum Power Supply AX860i (Bought this PS to replace the Kentek PS)
- N780 TF 3GD5/OC (GeForce GTX 780 GAMING) (traded Geforce GTX 780 card for the MSI version of the GTX 780 card)
OK... I got the new Corsair 860w power supply installed and i installed the new MSI GTX 780 video card with the specs above everything installed fine no problems and my son was playing the Bio Shock Infinite game on Steam and about 1 hour into the game he got a blue screen of death, says something like "to prevent damage windows is now resetting" and it turns off so fast can't read the rest of the message.
I'm going to here in a little bit and update all device drivers with MSI Live update utility and also update the motherboard BIOS again to v10.11.
I'm really confused here, I'm also going to take out some memory and try to run it with sticks only in slot 2 & 4 to see if it runs more stable like that, also should i update the video card to the latest driver, i know the latest is not always the greatest driver.
I want to think you guys again for your help & time with this issue. I really dont know what else to do here, everything is new in this PC.
Thanks

Z77A-GD65 + MSI Control Center (version 2.5.053) = FAN speed control issue

OK,
I've got Z77A-GD65 board and I am using MSI Control Center (version 2.5.053). I have one fan connected to CPU fan header and another fan connected to System Fan1 header on the motherboard. The problem is that while trying to use Smart fan control in MSI Control Center (under Green Power tab) only CPU fan changes speed according to load and the one connected to System Fan1 always stays at the same "System Fan1 Min" set speed. In BIOS the system fan1 is set to auto as all other options are constant speed from 50% to 100%, both fans have 4 wires, so they can change speed. I want both fans to change speed according to CPU load. I know I can use Y (split) cable to connect both fans to the same CPU fan header but I would like to avoid this if possible.
Anybody experiencing the same thing? Issue with bios? Control center bug?

As long as the amps of the two fans doesn't exceed the limit for the CPU fan header, go ahead and use a splitter. Not positive, but believe the fan header amp limit is 1A?

Boot issue with Z77A-GD65

I have a Z77A-GD65 board with 16GB of DDR3 RAM (4x4GB DIMMS) and an I5 Ivy Bridge CPU, Samsung 830 128GB SSD and 2x 4TB HDD's.
Last night my system was working perfectly. Today it won't boot into an OS.
When I would power up the system this morning, it started went through the Intel Matrix RAID BIOS fine then did a few status codes in the bottom right and ended up on A2 as the current code and sat there forever... I let it set for 15 minutes about no change.
I pulled the HDD's and SSD off first, same code
I pulled the USB and ethernet now the code changed to D0 still nothing, just hangs there.
I switched the BIOS switch to the second one, same result.
I pulled the BIOS battery and power and let it sit for a while, plugged it back in and put the battery back in... same result..
What's going on? I'm not sure where to go nor do I know the exact meaning of the codes given

Quote from: Svet on 15-September-14, 23:25:51
what is your bios version?
The BIOS that went nuts was A.B0, I did get it to boot though, just not with that BIOS...
I pulled all the cards, all the memory, anything plugged in HDD/SDD etc.. only thing left was onboard DVI and keyboard... cleared the CMOS again with the back button and it went into a never ending reboot loop.... switched it to the second bios via the switch on the motherboard, cleared the CMOS again, and bingo it booted... I think that BIOS 1 is corrupt... not sure what caused it, haven't done any updates or anything since A.B0 came out. And haven't made any hardware changes in that time either... worked great until this morning turned it on and boom It was stuck at A2 on the BIOS startup.
My question now is, how do I reflash BIOS 1? I read somewhere before I think that I have to do a multi bios update, but not sure how to go about doing that.

Z77A-GD65 Multiple BIOS Issues - B4 Hang, Splash Screen Blinking

Back in November 2012, I built a home server with a Z77A-GD65. Lately, I've noticed some strange things happening that I've been trying to research but to no avail.
First off, I get the B4 code hang-up whenever I'm booting. This doesn't matter if it's a cold boot or a reboot, it hangs on B4 for about 10-15 seconds, flashes 92 really quick, and then goes to A2 which it stays for another 5 or so seconds. After that I get the MSI splash screen for about 1 second, then it blinks 5 times. After that it goes into Windows just fine.
The blinking is a new issue, the B4 hang is not. I've read from multiple posts that this is a USB issue. When I disable USB legacy support, the issue goes away, but of course then I can't have legacy support. I have yet to figure out what exact device is causing it. In the process of trying to figure this out, I updated BIOS to A.A0. After updating to this version of BIOS the splash screen blinks 5 times before going to the "Starting Windows" splash screen. This is a more difficult issue to figure out why it's doing this because if you search for "BIOS" and "flash" or "flashes" or "flashing", you typically get results for flashing your BIOS. Hence, why I'm using the term "blinking". But even then I can't really find a solution out there.
I also happened to see that the website for the Z77A-GD65 is showing a newer BIOS version, but I'm unable to flash this (at least using M-Flash). I threw it on a USB, re-enabled USB legacy and whenever I click on it to install, the BIOS screen hard locks. The screen just freezes exactly where it's at in the BIOS and the mouse is dead. However, I can CTRL+ALT+DEL on the keyboard and it will reboot the system so I don't need to power cycle the computer. Not sure why this is happening either. Perhaps I need to flash this a different way? Maybe I don't need to flash this at all?
I could really use some input here on why this is happening.
As for the specs on my system, they're as follows:
i7-3770K overclocked to 4.2 Ghz by using the Turbo Mode in BIOS
32GB Komputerbay DDR3 PC3-12800 1600MHz DIMM with Low Profile Blue Heatspreaders Quad Channel RAM | 9-9-9-24 XMP ready
AMD PowerColor 7870 Myst Edition GPU - currently not overclocked although overclocking this doesn't seem to affect any issues
2 - 128 GB Corsair SATA III SSD - one runs the OS, the other I use to load games from
2 - 500 GB Seagate Barracuda 7200 RPM Sata II HDD's mirrored via Windows 7
1 - 750 GB Seagate Barracude 7200 RPM Sata II HDD
1 - 1 TB Western Digital MyBook USB 2.0 external
2 - 3 TB Seagate USB 3.0 external
ASUS DVD Burner - not sure which one, it's a cheapy $20 from Newegg
1 - PCI USB 3.0 expansion card
Antec TruePower New TP-550 Modular 550W Continuous Power ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Active PFC "compatible with Core i7/Core i5" Power Supply
NZXT Switch 810 gunmetal - currently have 4 fans running but plan on more, also the Switch 810 has the multi-card reader in the front with 1x SD Card, 2x USB 2.0, 2x USB 3.0
for peripherals
1 - Microsoft 360 Wireless controller adapter (legit one, not the knockoff although I had a knockoff prior to getting the real deal)
1 - Logitech Wireless USB Keyboard with Touchpad
I tried to be thorough. Thanks in advance for any help!

Probably a USB device problem.
This is a candidate, as well as mouse and keyboard. Disconnect USB devices one at a time to find the culprit.
A lot of devices running. PSU a +12V single rail or is it multi rail? A rail going to the graphics or components may not be enough amps. My best guess is the card reader.
For UEFI/BIOS flashing, select your mainboard here and use the forum flash method;
I'll definitely try unplugging some of these USB devices to see if that helps with the B4 hang issue.
As for the PSU, according to the description for it on Newegg: "Four industry-leading independent +12v rails are provided for more stable and safer power output." It has two rails going to the GPU. The GPU is a new addition to the system and so I wasn't running it until recently. The issues were occurring beforehand, but you're right that this PSU is underpowered for the rig considering PowerColor recommends a minimum of 500w. I'm going to be buying a larger capacity one sometime in the very near future. Any recommendations on good modular PSU's? What's a good way to tell what wattage to get?
Thanks for letting me know about the forum flash method. I'll be back later when I have some results.
