Higher Vcore? 645 ultra

Is it possible for MSI to release a BIOS with a higher vcore? I have read on this forum that intel stated the northwoods can handle more than 1.7v. If so why hasnt MSI raised their Vcore from 1.6? I have seen a vast amount of posts from MSI customers asking for a higher Vcore. The only reasons I can think of are that the 645 Ultra cannot handle a higher voltage or MSI isnt getting our requests. To clarify which board I own it is the MSI 6547 Ver. 1 AKA MSI 645 Ultra 333. Thank you for reading and please reply if you have any feedback.

Well you may be at the limit of your cpu, I personally wouldnt go higher than 1.75 volts ( which is really 1.7v because this board undervolts by .05v). I also think that the chipset can't handle much past 150 mhz not too mention how out of spec the pci and agp bus is (if anyone has taken this chipset significantly higher I'd like to see it). Also I had a Asus P3V4X (coppermine slot 1 mobo) and it was often suggested to put a heatsink on the clock generator chip (right by the ram slots, stick your finger on it and you'll see what I mean) to get higher fsb overclocking which indeed worked. Now I havent tried it on this motherboard because I ripped it off said motherboard and put it on my Diamond MX300 sound card (Aureal chip) because it was sputtering at high fsb overclocking (which solved that problem as well).

How to VCore mod my 645 ultra (MS-6547)

HI..
i got 645 ultra (MS-6547) and P4 1,80 @ 2,3GHz.. The problem is, that i can set VCore to max 1,6V, witch gives me.. 1,55V to 1,58V. I would like to set it higher..
HOW

Unless you really don’t care about frying your components, that procedure sounds like an impressively bad idea. I’ve also heard a rumor that there’s a “wire-wrap” way to unlock the multiplier on the P4s, but the same applies.

Max speed for 645 ultra?

What is the max processor speed for the 645 ultra? The manual says can support from 1.5 to 2.0ghz and up. How high does the "up" go. Would I be able to get the new 3ghz processor when it comes out? Right now I have a 1.6ghz (overclocked to 2.02ghz) and want a higher speed...
(oh yeah, I have the MS-6547 version 1)

Help with the MSI 645 Ultra!

I've got a very frusturating problem. I just bought the MSI 645 ultra mobo to upgrade my system, along with a brand new P4 2.0 GHZ processor and 512 mb DDR ram to go onto the board. My problem is as follows: The computer is not booting up. No OS, no BIOS, no nothing. When I turn the power on and hit the switch, all the hardware in the case starts up and sounds fine... but the screen remains blank. All four lights on the little diagnostic tool/usb port thingy that came with the board stay red, which, according to the manual, indicates a problem with the processor.
The processor is either bad (highly unlikely with it being an Intel chip) or for some reason its not working with the mobo. So, heres my question: Does an Intel P4 2.0 GHZ Northwood processor work with the MSI 645 Ultra?
Under the list of supported speeds, 2.0 ghz is not listed ?( . Can anyone tell me whats going on here?

Ms-645 ultra (MS-6547) CPU:RAM

Hullo,
I Just Finished building my new system. I am in the process of clocking it out. I used Fuzzy Logic 4 to find out at what speed my system crashes at. Fuzzy crashes any where between 139MHz & 143MHz system clock with CPU core voltage only slightly juiced to 1.5 volts.
This is probably not a good program for the actual overclocking from what I've read, but does serve as a good burn in utility. So I've decided on a 133MHz system clock in bios. Don't want to get too greedy right now as I am using stock H/S and fan. Next did a 5X burn in with Sandra and couldn't crash my system 49c idle 62c load. I must say this is a very nice mobo, extremely stable.
What I am having problems deciding on are my memory timings. This is my first MSI mother board and I'm not really familiar with the normal fast ultra and turbo settings.
Initially I set at the normal selection with CPU - RAM ratio at highest setting of 4:5 and CPU-Z gives me these memory numbers 166MHz & 2.5-3-3-7-11.
Next I tried the ultra setting and the highest ratio of 1:1 any other ratio causes system to lock up. CPU-z gives me these memory numbers 133MHz 2.5-2-2-6-9
It dosen't Appear that the Ultra timing mode offers any advantages over default memory timing settings. Are these words "Ultra" and "turbo" just marketing schemes meant to entice the common PC user, or are there some additional speed settings that go along with with the ultra and turbo modes that I am unaware of. Also after setting system clock to 133MHz My PCI & AGP are left untouched at 33MHz & 66MHz. I was expecting higher speeds. How are these independant? Where can I adjust these to clock along with the system clock. With those AGP & PCI numbers it behaves like a true 533MHz FSB system. I'm a little baffled with this new system. Any explainations would be greatly appreciated.

I'm not displeased, only a little puzzled. in fact i was counting on having to reduce the core & memory speed of my card just a little bit. to allow for a higher oc. Is this a 400/533 mobo manual says 400. Hmmm. I wonder what would happen if I put an 800 FSB cpu in here. bios system clock goes to 200. I happen to have one. this mat be interesting.

645 ultra - Dual Channel Memory?

Following great advice from initial poster to this thread , I've finally managed an overclock my 645 ULTRA, it's only taken me a year
Full system virus scan, and clean out.
Clean Boot,
Re-Set Ram CPU ratio down to give 266Mhz.
Turbo Ram Timing.
Ram Latency CL2
Ras/Cas Normal.
Al of which I was backing off, but rightn now seems to hold up
I was able to wind the FSB up to 118Mhz, clocking me at a mear 2.85 Gig (which for some reason is higher than 118*24)
the good thing here, is when the system did crash at 120, the bias did not re-set! which was happening in the past.
At 120 I got quite a lot of graphical artifacting, but my gcard was running hot since the air temp here is at about 25/26C with sumer approaching (don't help does it!)
Anyway, I'll be ticking off a few more tweaks tonight.
I did notice that this did NOT improve Aquamark, but added 1000 points to 3dMark2001, from taking it from 11500 to 12500. Benchmarks moving more from CPU/GPU to GPU only dependant. Codecreatures is a good bench also

MSI 645 Ultra - AmiBIOS 3.31a

Hi,
I did not plug in the connector for the CPU stock fan as my stock fan uses those white, red, yellow cable for power. Hence my motherboard will keep beeping that it's High Temperature since it "did not" detect my stock fan running.
My question is, how do I turn that alarm off? I remember doing it before but I forgot.

Woah .. there should be a way around this ......
anyone can help ?

MSI 645 ULTRA - DOES IT SUPPORT FAST WRITE -

MSI 645 ULTRA - DOES IT SUPPORT FAST WRITE -
coz i want to enable it so i can get higher 3dmarks score.
so i'm wondering if it supported but i think it doesnt but not sure.
k thx.

I am assuming here, that it is always on and that turning it off isnt a option via the less than robust bios' that MSI gives us. That being said, there is a utility called NVMax that allows you to switch it on and off as well as 2x/4x agp, assuming again, that you have a NVidia graphics card.
Try that Emazy, Im curious to see if you get lockups like I do when I check it off. For me at least, it appears to be on, but greyed out. Sisoft says that it is capable of fastwrites but not enabled.
As I mentioned before and as Assaf confirmed, the difference is negligeable and in most cases causes to instability.
I think Fast Writes was as big a hype as MMX was. :]

645 Ultra Memory Limitation?

I've had the 645 Ultra board for about 3 years now and I've had no problems running with 756MB of memory, one 512MB double-sided module and one 256MB double-sided module. I received another 512MB single-sided module for Christmas (from Crucial, using their selector) and I've been unable to use it in my system. It either reboots spontaneoously or else I receiver an error that says "can't write data 0xXXXXXXXX to location 0xXXXXXXXX can't 'write' the location" or else it says the same thing except it can't read instead of write. The memory location changes each time. I got another 512MB module that is double-sided but I still encounter the same problem but it seems more stable. I've set the BIOS to manual 100MHz FSB with 3:4 Memory ratio at 266MHz. I set CAS at 2.5T. The AGP size is 128MB. It seems that any amount of memory over 756MB does not work. Anyone else have a similar problem? I've read many of the forum issues but none seem like mine.
1.6GHz Pentium 4
MSI 645 Ultra 1.0 Motherboard BIOS 1.9
MSI Ti200 GeForce 3 with 64MB RAM
1.2GB DDR running at 266MHz
80GB IBM Harddrive
20GB IBM Harddrive
1GB Jaz Drive
CDROM
CDRW
SiS IDE driver 2.03.02.00
SiS AGP driver 7.2.0.1170

I had same problem...
I had 2 x 256 twinx llpt 3200 from corsair, no problem, running verry aggrssive timings and turbo timing.
added a 512 stick XLPT (faster still) and system would only boot at safe timing setting and cas2.5, with delay1T (2T)
I posted question on asktheramguy, corsairs very own and very responsive specialist, and he put it down to excessive load on the memory controller.
Also if you have different memory manufactures mixed in the slots, that's even worse, and you may not get the system to boot even after relaxing the timings
maybe lower speed 2100's and relaxd timing would be OK, but not much use with todays games
Or set memory timings to safe in bios...
So i bought another 512 3200XLPT stick and am selling the TwinX 2x256 LLPT's.
Well, I'm at 1gig at present 2 x 512 PC3200 XLPT (little over kill but fast).
With mem ratio set correctly and with my overclock this is running at about 380 Mhz (not the rated 400Mhz).
So upshot is, you'll need to get better ram, get a mached pair, and if your not bothered abour raw memory speed get something mid range cas 2.5 say....

Help requested with 645 Ultra-C with a PCI ATA/133 card fitted

I'm new here, so please bear with me if this plea for help is short of info :-
I built my PC 5 years ago, using a 645 Ultra-C board ( MS-6547 2.00 ) and have had no problems since - till now.
I recently installed a PCI ATA/133 card, mainly to be able to add 2 additional hard drives. It installed ok and the 2 extra drives are recognised correctly on the card's primary channel as is a DVD device on the secondary channel.
However, on initial booting, the card is interrogated to determine what devices are connected to it and then there is a delay of up to 2 minutes ( it feels like forever ) while BootMagic is being searched for/loaded.
It makes no difference if I swap the 2 drives and the dvd over or remove the dvd drive.
The bios ( AMI 07.00T 12/20/01 ) is correctly setup to boot from floppy first, then HDD1 ( connected to the mainboard's primary channel) and 'try other boot devices' is disabled.
I have no wish to boot from the extra drives, so is there any way of avoiding the boot system from looking there first ? Is there any other bios settings to consider ?
I'd be grateful for any hints/help.
Thanks.

Yes,
Go into bios and set boot sequence
Also go into pci controller bios, and set no boot
It's usually CRTL+A or CRTL+M keys on keyboard............
Controller cards will be main boot target, unless told
I have got the boot sequence set correctly - but I can see no sign of a pci controller bios option. Cntrl A or Cntrl M have no effect. Maybe the 645 bios doesnt offer those options.
I have never updated the bios - being of the 'if it aint broke dont change it' school of thought, so I may need to look at this area, now.
I'll be posting a question here about live update very soon - basically 'is it the best way to update the bios ?'
Thanks for your help so far

645 Ultra (MS-6547) Really Strange Bios Problem

I have just upgraded my pc with a 645 Ultra (MS-6547) mainboard with 128Ram and a Celeron at 1,7GHz. I have a hdd with a Windows 98 on it. The first time I booted after the change, windows starts up, it starts to detect the devices and is asking me to restart. At restart I see the video Bios and after that the mainboard starts beeping from the speaker and the display is showing lots of pages with special caracters and it freezes after a minute or so!!!!
I tried to upgrade the bios but al i got is this message:
"Phoenix Bios
D686
Award Boot Block MS-6547
Chipset/Flash port isn't available. The function will be invalid."
The really freakiest thing is that with another mainboard (same model) the problem is the same.
At first I thinked that is a boot virus, but I scanned the hdd on another system using f-prot with the latest definitions available(30.01.2003) and is clean.
Any ideas what could be?
thanks.

First of all: every one of the two mainboards started fine at the first boot, it loaded windows, started to detect new hardware then it asked me to reboot. After that it was hell! The graphics bios apeared and after that is starting to show something like this " %#^@&$(!#^ " all over the screen, is filling pages with this caracthers and beeping from the speaker. the d-bracket is with the 3 and 4 leds on red and i can't do a thing. the bios flasher (from your site) is telling me:
"Award Boot Block MS-6547
Chipset/Flash port isn't available. The function will be invalid."
the next thing i did was to try the old components on another pc based on an old i810 board. every one of them worked fine (individually and together). then I use the third board to remake my sistem from scratch with only new components (the old ones I was afraid to use), i instaled win98 on another hdd with drivers for the mobo. Everything was fine. The other hdd i scanned it on another system (winXP) with NAV2003 using the 05/feb/2003 updates and is clean. Then i saved the docs on it, formated it and copied (using pqmagic8 ) the partition from the new hdd with the working win98 on it. Installed the hdd and is ok. The the floppy and is ok. And now I am afraid to put the video card on it!!! I have talked with the service support and they told me to wait until they e-mail me an update program, new bios and instructions to recover my two boards. but that was 2 days ago... and i still got 2 freaked mobos!!!!
I will try tomorrow to recover the bios using the instructions on your site, hope it will work.
I still don't have a clue what the hell happend and what is the cause of this!!!

Old MSI 645 Ultra (version 1.1) won't Work.(period)!!!

OK VERY BIG PROBLEM!!!!
i built a computer from scratch, well old parts from my other computer!!the parts are 2.0gig intel cpu, 512ddr ram, 60gig harddrive, Msi 645 ultra(verison 1.1), geforce 2mx, and a 300W PSU. I put it all together fine I think . When i turned it on, Nuthing worked!!
I have the D-BRacket tool in the back and the lights first went 2 green top>1 green left, 1 green right which meant something like "Initialising Video Interface." and the computer didn't even work!!!nuhting, ZERO no bios no beep, but the power all worked. i fiddle around with things and Wen i turn it on again, the D-Bracket has ALL RED LIGHTS "CPU Damaged or inproperly placed" which is like impossible. ANd nuthing happens. I switch all my parts into my new one and nuthing is fried it all works!!put it all back together and the"Initalising video interface"lights happen again!!! i dunno whats wrong, maybe the mainboard partly fried or something i have no clue!! Monitor DOesn't show anything execpt a blank screen. Everything powers up but nuthing works!!

What do you mean by multitasking not working? How? What happens?
In any event, you should be able to switch to another App by clicking the Home button and touching the other App. Restarting the iPhone should not be required.

MSI 645-Ultra problem

Hi, I have some problems with my computer.
Here is my configuration:
CPU: P4 1.6 ghz
Motherboard: MSI-6547 645 Ultra
Memory: 512 Mo DDR 266 mhz
video: MSI 8836 GeForces II GTSTi64
I build up this machine in January 2002 by myself and it work fine. But, this week my computer start to turn off automatically and reboot, after it reboot i can work on it for about 20 min. and then the same thing append. It even append to me when i was in the BIOS, so for sure its not a windows problem.
I have try another video card and i still have the same problem.
Any help would my appreciate, thanks.

ATI has washed their hands of any future responsibility, so I am apparently stuck with a $200 vid card that doesn't work with my system.

MSI control causes higher vcore under load

Hello,
Why does Msi control center cause a higher vcore load than I set, by around 0.03-0.04 when overclocking in the bios I get lower vcore under load by 0.04?

Of what board and what system are you talking? >>Posting Guide<<
