Problem OC P35 Platinum + 8GB of CL4 memory with Q6600

Hi all!
I just lost that 1000 words post from power outage, so bear with me if I'm more direct to the point.
System:
P35 Platinum BIOS 1.9B1 (Vcore:1.375V, VTT: 1.30V, NB:1.550V, SB: 1.8V) 417MHz FSB x 8 = 3336MHz
Q6600 G0 2.4GHz @ 3.336GHz (42*C idle 68*C load)
OCZ Memory (OCZ2RPR800C44GK x 2 : AKA CL4 HPC Reapers) PC2-6400 @ 800MHz (4-4-4-15) OC @ 960MHz (5-5-5-18) VDimm: 2.2V
Geforce 8800GT 512 MB DDR3 (680MHz/1800MHz/1050MHz)
OS: Vista Ultimate x64
I try to push those memory sticks to 1000MHz. To do this, 2 ways I know: up FSB to 500MHz with 1:1 ratio or change ratio to 5:6 + up FSB to 417MHz. I tried both and here are the results:
Test the CPU OC = FSB: 417MHz x 8 = 3336MHz & RAM 834MHz (1:1) = 24 hours prime95 stable (small FFT)
Test the memory = FSB: 417MHz x 7 = 2919MHz & RAM 1000MHz ratio 1:1.2 = 24 hours memtest86+ v2.01 AND 24 hours prime95 stable (blend test)
Test them together = FSB: 417MHz x 8 = 3336MHz & RAM 1000MHz ratio 1:1.2 = memtest86+ stable (20 hours) but not prime95 stable. At those settings, SuperPI 32M would finish only 50% of the time (not exact in round)
I tried upping NB to 1.6V (Afraid to fry it), tried upping VTT FSB (What does that do...) to 1.4V-1.45V : no luck.
I know that below 1.55V my 8GB setup is unstable (crashed prime blend test at 18 hours...)
The other option is now trying with higher FSB. All those tests were done with 1.9B1 BIOS. At 500MHz FSB, the board wouldn't even POST. I then flashed the BIOS to 1.9B2 with success! I can now POST and boot with 500MHz FSB! I cannot load windows though which leaves me short of my goal. I tried some more conservative speed (470MHz FSB) and succeeded in loading Vista. Had a hard time thought, at that FSB speed, Vista was crawling and CPU and memory benches in Everest were about 50% lower than last stable benches. Something was wrong.
I was then wondering ways to boot Vista with 500MHz stable or make my two stable overclocks work together...
I read a post from someone stating that MSI told him to use performance BIOS P09 because OCing 8GB was easier with that BIOS. I did so. I could not boot in Vista (without OC, at default settings) because of nvidia driver (was able to boot in safe mode). I also read in that thread that BIOS P09 had problems with G92 videocards... I wish I could read German (or danish, not sure) because (save the thread I mentioned) the only forums talking about performance BIOS are German MSI forums...
I also read that BIOS after 1.3 are not good for OCing because of bad voltage regulation. I would flash back to 1.3
but the Q6600 Kentsfield is not supported before 1.6.
So I'm asking help at the same time from this board and User mod BIOS, was not sure to which board my thread would belong.
Thank you for you suggestions and/or advices concerning performance BIOS.
Jerome
P.S. Oh yeah! I also set my hardware OC settings jumpers to 333MHz which supposedly increase FSB stability... phew... I thought I would be direct to the point....

oops, u should have bought better memory, teach u for messing with manufacturers specs. No sympathy here
Well, it seems that the CS4 settings where exactly the rated speed for the GEIL Ultra Dual Channel modules, it's just that the (100% safe) pre-programmed SPD speeds are slower than the official rated timings. GEIL tells about that with all of their newer products, so timings I entered where not illegal for the modules.

P35 Platinum rebooting problem

Hello,
I have just registered at MSI Forums, as i have quite strange problem with my PC and i need help :azn:
My specs:
Motherboard : MSI P35 Platinum, bios ver1.9
CPU : Intel Core 2 Duo e6600 coolde with Thermalright Ultra 120a + Zalman 120mm fan
Memory: Mushkin XP2-6400 2 GB CL4-4-3-10
VGA : Inno3D 8800gts 512 with Accelero s2 rev2 + 2 Silverstone 90mm fans
HDD : Seagate 160GB SATA
Optical : Liteon DVDRW LDW-851S
PSU : Tagan TG430-U22 (i am running it at 'combined rails' mode, which has 28A rating for the 12v rail-information from the sticker)
I also have 3 120mm fans mounted in case
I have Windows XP SP2 installed
I took attempt to overclock my cpu and memory, and i managed to get 3.4ghz for cpu and 972mhz for memory (486FSB ; CPU Multipliter 7 ; RAM timings 5,5,5,15 ; RAM voltage 2,0v ; CPU voltage 1.4125v ; VTT FSB voltage AUTO ; NB voltage 1.45v ; SB I/O power 1.8v ; SB core power 1.15v), i am able to run Orthos Blend test (stressing cpu and memory) for about 8 hours (so it's pretty stable I think)
So, let's get to the point:
I am able to run my PC flawlessly all day long, but when i try to turn it on next day, it keeps rebooting itself for few minutes (it turns for about 10 seconds but the screen stays black, then it turns off and turns on again.....LEDS keep showing red/red/green/red indicating memory problem) and finally boots with 'overclocking failed' information.............i get to the bios, change ABSOLUTELY NOTHING, save settings (or not save..it doesn't matter at all) and then it boots and loads Windows no problem.......... what the heck is wrong?? Is it memory problem? Or maybe PSU? (I was using it in my previous PC)
Any suggestions ? :azn:
Thanks in advance

Avoid that one, instead go for:

A few questions regarding your current setup:
1) How are your system temperatures (CPU core temps, GPU temps, system temp etc). Use SpeedFan/Everest/Core Temp to monitor your system temperatures.
2) Is DOT disabled in BIOS? If not, please disable DOT immediately and see if there is any change in system behaviour.
3) Is MSI Dual Core Center installed/running when this happens? If yes, uninstall that tool for further tests.
4)
Try to loosen RAM performance settings for testing:
- reduce memory freqency to 667 MHz in BIOS
- manually set RAM timings to 5-5-5-18 in BIOS
- set memory voltage to 1.9/1.95/2V for testing
5) Have you installed the Vista Patch for more than 3Gb of RAM?
1) CPU: 31C 34C 31C 31C; GPU: 60C; System: 45C (speedfan). Here in Panama ambient temp is somewhere between 25-31C
2)Yes DOT is disabled all time
3)I never installed dual core center
4)Currently is running @800
5)I downloaded the patch and it says that doesn't apply to my system (Vista 64bit)
I found that when disabling the x-fi, the system runs OK. Is there any issues with that x-fi or 64bit driver? I ask because previously I was running vista 32bit with that same soundcard and everything was OK.
Thanks for the replies!

P35 platinum, memory and videocard questions

Hi folks.
I recently had a problem with an Asus P5K board in the sense that it doesn't allow use of 8gb of ram (despite saying it does) when you use 4x 2gb sticks. I want to replace this board with a P35 platinum but first I want to make sure my geil 8gb kit (4x 2gb DDR2 6400 sticks) will work (I'll be runnnig windows xp x64).
Also I have an XFX Geforce 8800 Ultra which has quite a big cooler, I read in some reviews of the board that the southbridge heatsink is too high for cards with big coolers like that to fit neatly. My question is will it still work? Can I screw the card in or do I have to live in fear of it plummetting out of the slot?
Thanks in advance for your answers.

I've tried 4 x 2GB OCZ DDR2 memory sticks. P35 Platinum detects 8GB main memory but shows usage memory as only 4GB out of 8GB. I've emailed MSI helpline if they can help out.

Problem installing MSI P35 Platinum & MSI NX8600GT & windows XP

Hi all,
I just bought my MSI P35 platinum mobo and MSI NX8600GT graphics card.
Was trying to install XP on it. During installation, got the following error message :
A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you've seen this Stop error screen, restart your computer. If this appears again, follow these steps:
Check to be sure you have adequate disk space. If a driver is identified in the Stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters.
Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.
Technical Information:
*** Stop : 0X0000007E (0XC0000005, 0XF748E0BF, 0XF78DA208, 0XF78D9F08)
*** pci.sys - Address F748E0BF base at F7487000, DateStamp 3b7d855c
Then it just freezes there. Any ideas how I can resolve this ? Please help
Thanks ...

Right Memory of a P35 Platinum

Ok just bought a P35 Platinum board, to replace my old board that I was having problems with. My processor is a Intel C2D E6400 2.13 Ghz L2 2MB. I have just bought OCZ 2GB (2x1GB) DDR2 1066MHz/PC2-8500 Dual Channel memory. Is this ok? Or have i Messed up? Also what tweaks will I have to make to get this mem working to its full potential??
Thanks

P35 Platinum Problem

Update:
Have not got standard memory yet so tried other options...
Replaced floppy drive with one that I verified was working, but no change so floppy drive is ok. Another possibility ruled out.
Reseated memory, floppy cable, graphics card multiple times, no result.
Changed FSB jumper to 333 setting, no result. Changes back to 200, result!!! Booted to bios config multiple times. Some times I got 4 red leds though, in which case the system stopped and rebooted. Then booted to bios again. I decided to try again to reflash the bios to 1.1 using ctrl-home keys. This time it worked. Verified bios is now v1.1.
Started getting cmos errors though. The bios gave me the option to reset to default values, when booting. I did this, and rebooted. The system stopped working again then, showing two green lights, two red. :(
I reset the FSB jumpers to 333, turn system on/off, switched back to 200. Again, I found I could now boot to bios again.
This is as far as I have got. Havenot been able to boot to OS yet. Any advice appreciated.
Starting to think this is not just a bios issue.... :(

2 x Hitachi Deskstar T7K500 500GB

Update:
Before my last post, I had previously flashed the bios back to the original bios which originally worked for me (1.1, the version which came with the machine, got it from the web site), but I ended up with the same problems. Last thing I did that night, was flash the bios to 1.4b... bios, but seeming same problems reproduced.
I was ready to return the motherboard on Saturday but curiosity got to me so I decided to follow Bosskillers advice and try out some other memory. Not that I doubted Bosskiller but this meant I had to bite the bullet and go buy some vanilla memory. Another 128 euros less in my pocket, after replacing my PSU also
Before installing the memory, i decided to try to again boot the PC (using bios 1.4b... beta) with the high perf memory. Didn't work the first couple of times, then it did! OS booted even, first time in a week. Occasionally (30% of boots) I got the four red lights followed on the next boot by an error messages highlighted in red saying the previous overclocking settings prevented the machine from booting, did I want to keep current settings or reset them. In each case, I kept the setting and simply rebooted.
I then noticed I had not switch the FSB jumper to the 266 setting. Not sure if this matters, as I though bios automatically detects / sets the correct FSB setting in any case. This seemed to improve matters a little.
I then changed the memory, and things improved further. I am now able to boot most of the time, only seeing the 4 red lights when I cold boot the machine after it has not been used for a while (this happens 100% of the time). While running, it seems stable. If i do mess about a little, and constantly hit the reset or main power switch on/off every 10 secs, I will occasionally see the four red lights, or 1G1R2G so I avoid this
Will run the memtest tools you suggested. I am not convinced the high perf memory is bad yet. Will try out some more tests on it at a later date though. The cold boot issue sort of suggests a PSU issue to me but I am unsure. In any case, my Antec power PSU is not in yet , but will install when I get it and hope it resolves the residual issues.
Much appreciate all the help from folk, especially Bosskiller. It has been interesting, I have learned quite a bit I believe.

P35 Platinum and MSI 8600 GT problem

I have a problem with the computer locking up. It will do it on certain web sites, clicking around in Media player and other programs. I tried everything I could think of. Finally I Got an 8400 video card locally and everything is fine. My question is, since the 8600 GT gets all of it's power from the PCIE slot could it be a voltage problem? If so, I see no way of increasing the PCIE voltage in the bios for this MB.
Any ideas before I send this card back?
Thanks,
Bill
Msi P35 Platinum Motherboard

2 gig Corsair XMS2 6400C4D Dominator Memory

It locked up with default bios settings and no overclocking. I didn't overclock the video card at all. I tried everything. Since I put in a temporary 8400GTS I have the processor overclocked to 3.3gig and everything is fine. Could the 8400 need less power than the 8600GT and if so is there a way to increase the voltage on the 16X PCIE slot? This is a MSI MB and MSI Video card so I would expect them to work together.

P35 platinum crazy problem

we're professional pc producers
we're building 2 workstations with this components:

now:
with 700w cooler master psu system wont boot or post, fan start about 3 sec then quit
no beeps, no leds.
with others psu's EVEN CHEAP 450W OR 500W system post FINE!!!
AND THE 700W COOLER MASTER IS WORKING PERFECTLY! cause it works with 10/20 other machines.
we've updated every kind of bios release
we've switched 667,800,1066 memory from kingston, a-data o buffalo
we've unplugged all peripherals
so. any1 ideas?
the problem is the same with all 2 mobos

They suspect a ground issue, but also have been reported several 12V rail "abnormal behaviours".
hi all, thanks for posts. we already switched to enermax psus and everything is going just fine.
but the question about cooler master psu still remain...we've done some electric tests, but we didnt find any ground problems...regard the 12V rail...an "abnormal behaviours" is a *very* generic definition of the problem, so we dont understand where we have to look...
It would be nice to find where really is the problem, so we really can say they products are "mediocres" and feel free of suggest them or not...this way product judgment can be based on real technical facts and not personal opinions...

P35 Platinum - 4GB Problem

Hi guys, hope you can help me.
First things first, my system is as follows -
Intel Q6600 Processor - B3 Stepping
MSI P35 Platinum - BIOS flashed to 1.3
4 x Transcend 1Gb DDR2-800 Modules (5-5-5) (All Identical)
Gigabyte nVidia 8600GTS 256Mb
420Watt generic PSU - 3.3v/22Amp 5v/36Amp 12v/18Amp (It is also brand new)
The problem:
Boots fine with with up to 3 RAM modules installed. But refuses to POST with all 4 installed and hangs with the post code indicating the memory detection test (Red Green Red Red). I have removed and reseated all of the Modules, and tried them all in different slots to no avail. I have also tried unplugging all hard drives and DVD drives to see if it would get through POST, but this did not help.
I dont believe its actually a faulty RAM module as removing ANY of the modules will fix the problem, allowing me to boot with 3 DIMMS installed. And the system boots fine with each module installed by itself.
I have also changed the RAM timings from Auto to manual and fiddled with the timings, and gone back to "By SPD". Which did nothing.
Any thought and help would be appreciated.

What is the stock memory voltage? It should be listed on the sticks. Make sure you set this voltage in the BIOS.

Return it and get something with more Amps on the 12v rail. 18A on the 12v just won't cut it.

[P35 Platinum] Memory lost: 4 GB = 3,25 GB?

Well... I now have system for some time now and works fine, but there is another problem: my computer sees only 3,25 GB memory, while I have 4 GB.

I understood very well. I am an Software Engineer. I can refer you to this MSDN post for more information on the subject:
http://blogs.msdn.com/hiltonl/archive/2007/04/13/the-3gb-not-4gb-ram-problem.aspx
A qoute:
"Significant chunks of address space below 4GB (the highest address accessible via 32-bit) get reserved for use by system hardware:
• BIOS – including ACPI and legacy video support
• PCI bus including bridges etc.
• PCI Express support will reserve at least 256MB, up to 768MB depending on graphics card installed memory
UPTO 768MB depending on gfx card installed memory..
This means that essentially you have about 512-768mb ram that you cannot use as the OS isn't able to use the address space as it is reserved for the above mentioned devices.
EDIT:
This is also true for AGP graphics cards
Sorry about the first post was very vague..!
I need to remind to all. To have gfx to share the physical memory, is only when your gfx does not have enough RAMDAC capacity itself.
For example, if you PCIE/AGP card is only 256MB and you have 2GB RAMs. Under non-graphics intensive enviroment, you will still see 2048MB RAMs detected. If under graphics intensive operations and the system finds that 256MB is not sufficient, it'll borrow the part of the "allocated" size from the physical memory. Most commonly seen in boards supporting AGP cards, where you'll see AGP Aperture Size. This is where you'll be able to allocated 16MB to 512MB depending on your board and BIOS for the gfx, if in any case it needs to borrow some.
Example, I've allocated 512MB out of 2048MB for my 256MB gfx, I'll still see about 2048MB physical memory while system is not using graphics intensive applications. If I run a rendering application, example LightWave 3D, the application finds 256MB isn't sufficient to do rendering of graphics, it'll communicates with OS and from OS to understand how much physical memory is allocated for borrowing to suffice the gfx for the job. OS will detect BIOS settings and return information to application. Thereafter, application will initiate the amount of memory that needs to be borrowed, example 256MB. From here 256MB will be blocked specially for the gfx and application to complete the task without disturbance. This is when you'll see a drop in physical memory detected.
Another common scenerio is onboard graphics with shared memory of up to xxx MB, which is commonly found in laptops.
I just hope that this will strengthen the point brought up as it is not only software based but also hardware based for this to happen.
Best Regards.

P35 Platinum and Patriot Memory DDR2 PC6400

Hello,
I've tried to adjust RAM Timings, RAM Voltage and RAM frequency manually on my P35 Platinum with BIOS 1.4. I had a reboot loop at CAS 4 so I've tried to put at 1000 MHZ ratio 2:3 after a clear CMOS. It's working.
Now my Patriot Memory is working at CAS 5 ratio 2:3 2,2V and 1000 MHz.
Should I carry on my "quest" to CAS 4 or are these settings good enough? I'm quite lost.....What should I have to do?
Does Patriot Memory owners experienced the same issue? Why can't they be set to CAS 4?
One more thing: After the Post, the Marvell Bios loads but find no hard disk on adapter 1. With Bios 1.1, there was no problem. Do you have any explanations?
Thanks

Hello Spikape,
please list full system specs and provide more information about the specific model/type of Patriot Memory you are using.

I had a reboot loop at CAS 4
Can you try to be more specific about this? Was it an on-->off-->on-->boot cycle or did your system reboot multiple times?

P35 Platinum Memory/Boot Issues

Cpu: e6300 core 2 duo
Motherboard: MSI P35 Platinum
Memory: Generic? hynix chips pc4200 (can get a pic of the stick if you want) 2x 512
Vid Card: ati x1600 pcie
Hard drive: 250gb sata
PSU: Xclio stablepower 500w
When I start the computer, the normal boot reboot sequence starts and eventually the LEDs stop at RRGR. The memory I'm using is from an oldish hp pavilion a1642x http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00787158&lc=en&cc=us&dlc=en&product=3304173# who's mobo went out. I'd like to know if maybe theres something wrong that I'm doing or if both sticks happen to be bad or something else that I'm missing? I've tried different combinations of slots/sticks and tried manually setting the fsb with the JB1 and JB2 jumpers. Someone said the 1.3 bios was picky about ram but I'm not sure how to check what bios version it is since I cant get that far =p

Need Help with Memory OC to 1066 on P35 Platinum Combo

Hi,
I've been trying to get my Corsair Dominator memory to 1066, but everytime I change settings, the system will not post. So far I've:
- Disabled EIST & DOT
- Disabled 'Configure DRAM Timing by SPD' and set values to 5-5-5-15 (left all others as is)
- Processor reports 333x9
- Set ratio to 1:1.6.7 bringing adjusted timings to 1109. I also have 1:1.2 for 1332 & 1:1.50 for 999
- Memory voltage set to 2.1
Not sure where to go from here as other MS reported here seem to have different settings than the P35 Platinum Combo.
Specs are:
- Intel E8400 3.0GHz Dual Core (45nm)
- MSI P35 Platinum Combo
- Sapphire Radeon HD 3870 512MB GDDR4
- Xigmatek NRP-MC651 650W Modular PSU
- Corsair Dominator 4GB 1066 DDR2 RAM (PC2 8500)
- Samsung 22X DVD Burner
- Lexa Blackline Case
Any advice welcome -- I'm at a loss.

Hi,
You would probably better off, posting in the Overclocking section than here.
