2.26GHZ overclocking = blue screen of death!!

[gf4200isdabest]

When I overclock my 2.26GHZ Northwood (533MHZ) past a FSB of 144 (2.44GHZ), i can't load my OS. I just installed windowsXP to see if it was any better than 2000 for this oc'ing but alas...both give me a blue screen of death during the initial OS loading when the system is overclocked too much. This is really disappointing because I'm sure that this CPU could go a lot higher than 2.44GHZ. Could someone give me some advice as to what could be the problem? Also, when overclocking, should I change the voltage to anything (CPU, AGP, VDIMM)?

On a different note, anyone know why my mobo name isn't showing up with 3dmark's results? Could this mean I haven't installed proper drivers for it??

Help is appreciated!

well it means it s unstabble a that speed. try upping the voltage a bit. and keep doing it to till it is stable. though Iwouldn,t go beyond .2 volts over spec.

also you may just have to live with the fact that your cpu is a poor overcocker of the batch. Not all northwoods can overclock well.

raise VDIMM to 2.7 or 2.8 and Vcore i'd say is say up to 1.75 V

also check the mem ratio and the memory timings mem ratio should be 4/5

also the dividers (most likely your problem) you should either lock the AGP and PCI or set them to 1/4 or 1/5 for PCI and 1/2 for AGP

my friends 1.6A hit 2.8 Ghz on a abit BG7 air cooled with intel retail HSF so i think it could be the motherboard you maybe something you did incorrectly

what kind of temps are you getting?

Up the vcore to 1.65 but don't push it any higher, or u will risk killing your P4. And see what happens then

Adul; i'm not ready to call this a bad overclocker yet because it POSTS and runs DOS @ 2.85GHZ. This is without any modification to voltage so i bet if properly done it could hit 3GHZ. Its Windows2k and XP that i'm having issues with...maybe i should make a FAT partition and see what Windows98 thinks about this...lol...98

My motherboard doesn't seem to do 4/5 RAM settings. it has 4/3, something i can't remember, and 1/1 but in all cases the 1st digit is greater or equal to the 2nd.


"also the dividers (most likely your problem) you should either lock the AGP and PCI or set them to 1/4 or 1/5 for PCI and 1/2 for AGP"

whaaa? Run that by me again...can you rephrase and/or explain that in a bit more detail (especially if you think that's what is causing the issue).

So i should try to get the vcore to lets say 1.65 and the VDIMM to 2.7. Can someone confirm that those would be "safe" to do? I'd hate to fry this computer because other than the overclocking, I'm very happy with its performance...

pretty much all DIMMS will do 2.8 V and out of the 20 or I've worked with 2.8 V did not kill em

Mushkin even recommends 2.7 or 2.8 on theirs for "extra stability)

the dividers thing is easy it should be in the same places as where the FSB is found

your FSB is 133 Mhz so your AGP should be set to 1/2 ie 1/2 * 133 = 66mhz which is normal for AGP (do not use 2/3)

PCI should have at least a 1/4th PCI divider ie 1/4 * 133 = 33 mhz which is normal for PCI

as soon as you bump up ur FSB you should be able to set the PCI to 1/5 or maybe 1/6 otherwise you can lock it at 33mhz and 66mhz effectively independent of your FSB and it is usually better to use a divider and keep these values close to spec rather than lock them

i run 1.7 V on my northwood and it has been flawless so far. It was not totally stable at 1.65 for me in JK2 but the bump fixed all issues

and also I am very sure the epox 4g4a + or no + offers a 4/5 mem ratio so the mem runs at 1.25 * the FSB

so at 166 FSB you have have mem running at 208 or something mhz DDR

also a few ppl have noticed stability issues cropping up when using a double sided DIMM in any other slot besides one or had problems running 2 sticks together at all i think WingsNut PEZ had an issue with this

anyway your problem could be running 2 sticks of memory or more so you can try leaving one stick overclock it and see if it will do it with 2 sticks

my 512MB is one DIMM...So no problems with that kinda junk...

I am at work right now so I don't have the bios in front of me. When i get home in 5 hours I'll see what I can do about the PCI and AGP ratios...

if it does offer 4/5 mem ratio, I'm not finding it. It has auto, 4/3, something else, and 1/1. That something else isn't 4/5...Do I need to change some other setting for it to allow me to get 4/5?

Argh....8 hours of sleep over 3 nights is taking a toll. I can't even understand things anymore.

some tidbits:
"First off, the CPU select jumper. If you set it at 'auto' or 100, your available memory ratios are 1:1 (200) or 3:4 (266) only. This freaked me out at first, cuz I was looking for the newer 333 4:5 ratio. Apparently, if you set the jumper to a 133 proc, 333 4:5 is now available, and we have some new ratio's:
4:3=DDR200
1:1=DDR266
4:5=DDR333 "

'That's important. If get a chip that WON'T do 2.4 or over, use the 100 jumper. Example: say your chip maxes at 2.4, and your memory at 400. With the 100 jumper (4BDA style), you're at DDR 400, but with the 133 jumper, you're at DDR 380. '


this seems akin to my issue but I'm not understanding anything that guy is saying. I guess its a combination of little sleep and no experience with modern motherboards. Could someone please translate that guys conclusion into a step by step process I could do to solve the problem...

*sigh*

it means set your jumper to 133 FSB and you will get your 4/5 mem ratios

4 = fsb
5 = mem

for every 4 mhz in FSB there is 5 mhz in Memory

you probably have your jumper set to the 100 (400 mhz bus) instead of 133 (533 bus) and if you set it to 533 you will get the correct ratios for your cpu

and the divider thing will probably fix itself once you set the FSB jumper to 133 i think

Make sure you have the latest BIOS for your system (this is very important in some cases) and try a vcore of no higher than 1.65. I can do 2.0 GHz @ 2.4 GHz comfortably at 1.6 volts.

Adul; i'm not ready to call this a bad overclocker yet because it POSTS and runs DOS @ 2.85GHZ.

That doesn't mean anything at all. DOS is a very simple OS that doesn't stress the system or its timings at all. It could well be that you simply have an overclocking dud. No overclocks are guaranteed and buying hardware on the basis of overclocking is foolish.

Make sure your RAM stick is in DIMM 2.
