Need help with 870a-ud3 mobo. - Page 2

post #11 of 12
Thread Starter 
Think I'm hitting a thermal wall on the motherboard.

Set the mobo to 223 FSB and everything at stock settings manual. Can't pass 3-4 hrs. Than can't pass the 1 hr mark with additional voltage. I gave up at the point.

Set FSB to 200 and my last stable OC settings. System seemed slow till a few restarts.

Thanks all. Guess I'll pay more attention my next build. This was my budget system.

Guess I spoke too soon. Get my system stable (hopefully, still 16 hrs to go) at 223 FSB.

Ran prime95 at 233 FSB with all multipliers as close to stock as possible and passed 28 hrs. Than restarted the whole OC process again.

Now off to work on my ram.

I'm still thinking NB voltage does nothing. Didn't seem to help stability and increased temps (for my GPU).

Current at 233 FSB x 16.5 = 3679.8 mhz @ 1.45v
HT at 2007 mhz
NB freq at 2672.2 mhz @ 1.4 v
Ram at 743.3 mhz @ 9-9-9-24-40-2T

I'm hitting the same temps under load in prime as my non FSB OC (55 usually and a few spikes up to 57). This is as far as I'm willing to push my CPU.

All of this on stock NB voltage including original 233 FSB stability test (with "stock" settings).

Only real difference aside the small gains is my ram went from 667 mhz to 743 mhz. Hopefully I can bring the timing down and re-enable 1T.

I feel like I just made a huge circle. I could have just lowered my ram and bumped the FSB and it should have been stable.

Thanks all. If anybody can help me with RAM timing, I have a new thread in the AMD memory section.

Really think my previous issues was an issue with the ram dividers. Certain dividers just don't want to work.
