890GXM-G65 Voltages

post #1 of 9
Thread Starter 
Hiya all,
Before I start, I just want to say I know that this board isn't great for OC'ing to 4.0 All this is done with my current sig rig.

Currently I can get to 3.87 Ghz at 215 bclk and 18 multi that runs fine on prime95 for over 4 hours until I stop the workers. If I bump up to 3.97 Ghz by upping multi to 18.5 I crash in about 20 minutes. Same story if I go to 220 and 18. Don't think temps are an issue as I don't go above 45C at 100% load. I get to this by using stock core voltage of 1.35 V.

Anyways I want to up my voltage a bit but my BIOS has the options greyed out. My revision is V1.6. What am I doing wrong here?

Not great but definitely not safe either. This board is known to blow up with overclocked high TDP processors. I don't recommend any overvolting whatsoever.

In all honesty I don't even really mind if that happens.
Just gives me an excuse to move to sandy bridge when the new mobo's are out. Hahah.

Would you say 3.87 is fine at those temps and voltages?

I blew up that same mobo by upping my voltages, if you're at stock volts then you're fine

I notice that on xd 1771's 4+1 post, every one of these mobo's with problems were x6.
Has anyone had issues with an x4?

x4s had problems on these boards too I think. See my horror stories list in my article in my sig (orange-coloured link). Sadly nowadays horror stories are coming in almost daily, the list is so long now

That is really to bad. I ran an overnight Small FTT test over night at stock voltages 3.87 ghz and I crashed only as I checked it out after about 14 hours.
I really want to be able to hit 4 ghz with this chip because I know that I can do it, I just don't want to risk frying all my other components.

There really are no better AM3 mATX boards?

Biostar TA890GXE
Gigabyte GA-880GM(A)-UD2H (after you add MOSFET cooling)
ASUS M4A785TD-M EVO (after you add MOSFET cooling)
ASUS M4A88TD-M EVO (after you add MOSFET cooling)
Safe/good (with proper MOSFET cooling) for overclocks up to 1.5V I'd say

Hmm I guess I have to decide now if I want to get a quality AMD ATX board and use my ugly antec 900 as a gaming HTPC or if I want to change to a mATX sandy bridge board and keep my beautiful P180.
