HT Link Safe @ 915?

post #1 of 10
Thread Starter 
Hey, I'm trying to get my processor to 3.2, but i cant do it with a 9 or 9.5x multiplier because for some reason my motherboard doesn't like FSBs higher than 310ish.
so I'm thinking I could probably get to 3.2 on my current 10.5 multiplier, but I'd have to drop my HT link multi from 4x to 3x, because at 4x, with a 305 fsb, the HT would go over 1200 (its currently at 1144 with a 286fsb) and thats too high, and my comp wont boot

However, my comp does boot even when the HT link is even as low as 880, but I was wondering if thats safe, or if there are any noticeable performance losses when the HT link is that low, basically would my comp be faster at 3.0 with a 1144HT or 3.2 with a 915HT?


Current Setup:
3003mhz
286FSB
10.5x multiplier
1144mhz HT
RAM @ 858Mhz (429x2)

Proposed Setup:
3202mhz
305FSB
10.5x multiplier
915mhz HT
RAM @ ???Mhz

50% of the OCN community uses AMD processors and no one knows the answer? lol

You only posted 20 minutes ago... The answer is--run some benchmarks and see which is faster--that's the only way to find out. From what I remember on my last AMD system (S939), I didn't notice any performance difference until I dropped below, like, 700MHz HTT. But really you should run benchmarks on either config and see which works the best for you--it's the only way to know.

CPU speed is what you're after on AM2.... it's safe to run a lower HT.

HT of 1000 is ok anything over is risky.

My HT Link is currently 842

I think that's true for 939.... AM2 setups can run well at 1100-1200 HT.

Yup. Mines around 1100 right now and is perfectly fine. I've heard some boards like it up to even 1300-1400

Erwin_rommel, the lowest I'd recommend for an HT speed would be 700mhz. At 650mhz HT you'll start to see instability issues. There is no performance increase or decrease with running a high or low HT speed. For AM2 processors, it's typically recommended amongst others that you try an HT speed between 1200-1400mhz. Apparently the high HT speeds "help" the overclock.

Hope this helps

It really depends on the motherboard though--my crappy ASRock S939 board ran perfect--actually better--with a HTT of 1150 vs. 1000 stock. I think this varies from board-to-board--which is why it's important to just get your hands in there and work through it--if something is unstable, then that's a no good HTT speed. Good luck!
