5000+ BE stability issues.

[GooeyGus]

Hi all, its my first time posting here and i hope you all can help me out!

Processor: AMD X2 5000+ BE
MoBo: Gigabyte GA-ma69gm-s2h (has the good bios with all the OC'ing options)
ram: kingston 1gb 667 (cheap stuff...)

Ok here goes... So I've OC'd my cpu to 3.0ghz on the stock (1.35) voltage and its 100% stable, passes prime 95 like a champ, never going above 35-36c. All i did to reach this goal was increase the multiplier to 15. Cake.

Anyway, so i was hoping to get it to 3.2, since from what i've read 3.3 is close to the limit as far as stability goes. So i increased the multiplier to 16 and the core voltage to 1.4v because all the reviews so far have said its perfect at 16x with 1.4v. Not the case with mine. To even get the computer to boot i had to up the vcore to 1.45. And, as far as just running the computer, it runs great at 3.2ghz with 1.45v but i cant get it to pass the prime95 test. It gets a rounding error after only a few seconds. Temp is not the issue, even at 1.45v with prime95 it never passed ~42c.

Any tips on how i can get this thing to pass prime95 at 3.2ghz?

thanks in advance!!

Hello to the Forum. I new myself but here's a bit of help that should work.

Try just upping the FSB to 213-214 with multi at x15 still 3.2Ghz with Vcore @ 1.45 or maybe push to 1.5, with temps that low. Should do the trick, i'm sure that kingston ram 1:1 with FSB at 213 will be fine, if not raise Vram by 0.2. Plus your HT link will still be below the 1100 area that tends to mean anything higher needs knocking down HT link speed to x4.

Hope you get her to 3.2Ghz GooeyGus.

P.S I seen another fella on here overclock his to around the 3.2 area 'Akilies' i think his screen name is.

Look at your kingston chips. Is there a logo like an O with an M inside? That's Micron chips. The letters below it is the one to look at:

D9GMH is the best. If that's the case, you can o/c your ram to 1000mhz with higher vdimm.

Easy way: try 200 x 15.5 = 3.1ghz

Hard way: read up on overclocking AMD. This official guide from nvidia applies to nforce chipsets, but the concept is the same: find max HTT(FSB), MHZ(CPU) & MHZ(DDR2). A little long, but works for me.

Hmm.. The logo on the side of the chips looks to be a little "d" shaped thing... not the same logo as the pictures. I took a picture that I can upload if you want to see it. The only downside to my BIOS is that it doesn't have the .5 increments on the multiplier... it just goes 15, 16, 17 etc etc.

Do you have any good links to this info?

thanks a bunch!

Sorry I thought I pasted it in here. Here you go:

Do you have your memory devidor set at 667Mhz. Sounds like that is what is holding you back. I'm currently running my 5000 Black Edition at 3.28 Ghz 24 hour Prime stable using 205x16. Thats at 1.45V. Remember when you go to the 16x multi, your memory will run at 800Mhz unless you use a devider. By the way what are you using for a cooler/heatsink? What are you using to monitor temps. When running Prime95 my temps were hitting 57 but it idles at 30. Wish we could get true core temps with these Brisbanes.

When i get to 16x, i check the ram speed and since the divider goes from i think 9 to 10, its only like 320 (so, i guess 640mhz respectively...) I really cant figure it out... i'm only running 1gb of ram right now, and i doubt that would have anything to do with it, but i ordered another stick that should be here on tuesday so we'll see if anything changes once i have 2gb in there. Recently, i also got a rounding error after about 5 hours on only 3ghz!! The temps seems perfectly cool using both easytune and the new AMD program (overdrive i think it is..) under heavy load with 1.45v i couldn't get it above 45c. The cooler is a kingwin revolution.

We have a similar config, since I also use 667 DDR2 (Crucial Rendition) but it's forced to run at 800 (upped voltage from 1.8 > 1.9) with my CPU set at 200 X 16 = 3.2ghz (@1.4375volts). My ram divider is set to 800mhz or CPU/8 in my bios. These are the lowest possible voltages I run passing 12hrs of p95.

It's strange that my idle temp hovers anywhere from 41 > 49c, but never goes above 59c on load (Arctic Cooling 64 Pro HSF).
