RESOLVED - F2-8800CL5Q-8GBPI and the ER45-UD3P?

[thetruth]

of course this is the EP45-UD3P

Resolved - Updated the bios to FE last night. Memtest and Prime95 have worked flawlessly so far. I left prime running all day and will be interested to see results when I get home from work. While running it this morning I accessed the internet, opened outlook, and turned on the tv tuner with windows media center and the threads did not abort or show any errors before I left.

processor is e8400 running at 3.717 with below settings have not tried going higher yet. memory @ 1101, 5,5,5,15

I started out with the following changes from the git-go, and I will try to ratchet 3 of them down over the next few days.

CPU vcore @ 1.325
MCH @ 1.3
trfc @ 72
FSB @413
latch @ 2.66D
But the dram was left on AUTO and checked out in the health section of the bios @ 1.9v.

About time Gigabyte fixed their bios!

prime95 ran for 12 hours 40 minutes with 0 errors or warnings

Glad to hear it and thanks for the info

I have the same set up, and seem stable at 400FSB with settings similar to yours, and am just now looking into how to push it further. At 450FSB it boots, but Prime95 fails after a few minutes. If you've made any progress, please post.

[GSKILL TECH]

Did you raise the CPU FSB Termination Voltage?

Thank you

Here are my settings. The system passed ~5min of Prime95 Torture test. So far, I have not been able to get past 450FSB. Anything more and I can't boot. I'm not sure exactly what settings to focus on next, but I read some DRAM timings, such as tWR could be responsible for boot failures.

i lowered the vCore and MCH core a touch, and can just barely boot at 455FSB. when booting i either BSOD at the point of the four colored spheres coalescing during 'starting windows' screen, or the boot completes but prime95 fails instantly. temps are fine; 30c idle up to 48c full load. i'm not sure where to focus next. memory is locked at 900Mhz and its rated for 1100, so that should be fine, shouldn't it? voltages could go up a little, but not in parallel with the FSB much further. also, i've had little luck finding authoritative info online. if anyone has any suggestions, please post'em.

[GSKILL TECH]

Maybe not enough CPU Termination Voltage? Sounds like a voltage problem, so you need to find out where there is not enough voltage.

Thank you

Not sure if faster is possible, but will try at a future date.

i was only stable at 4Ghz; 450FSB, and 9x multiplier.

i hope its not inappropriate to post this question to a support forum. plz forgive if so.

i'm wondering if the e8600, which i understand has a 10x multiplier, would work in my system with its 450FSB, and give me 4.5Ghz. does anyone know if the added clock multiplier mean lower FSB, or otherwise adversely impacts OC performance or not? could it be as simple just dropping it in, and OC'n it, fully expecting a 450FSB?

thoughts?

[GSKILL TECH]

It depends on if the CPU can support it, and if you have the right voltage. It is much easier to work your way up to see if it can do 4.5GHz, rather than guessing what voltage it needs for 4.5GHz. Guessing is definitely not the way to go.

Thank you
GSKILL TECH

[ooostephen]

mm...blind guessing is bad, k.

just wondering that since my E8400 handles 450FSB, does that mean the E8600 would too? Or, does the E8600's 10x multiplier mean it craps out at lower FSB speeds?

[GSKILL TECH]

No, it should be able to, it simply allows a higher CPU ratio, which is why people purchase CPUs with higher multipliers, or unlocked. =)

Thank you
