GA-EP45-UD3P, E8600 overclock problems

Re: GA-EP45-UD3P, E8600 overclock problems

I'm not sure what happened here. I was adjusting my vcore and now this is what I'm seeing in ET6. All of my bios settings are exactly the same as the last post. I reset the bios back to optimized and started over and I'm still seeing the same levels in ET6. My temps are higher and Prime95 gives an immediate error.

Looks like adding the raid array is what caused the issue. I took out the raid and put the single drive back in and ET6 shows the right numbers.

Why would adding two raid drives in place of a single drive cause the voltages to move like that?

I'll take a stab at that-- the raid drives are holding the configuration (back up) bios?

Chike, I just got back in town. My EP45-UD3P / E8600 is running 8GB of G.Skill (4x2gb) F2-8500CL5D. I wish my EP45T-USB3P / Q9650 was as easy to OC. My E8600 seems to handle more voltage. It ROCKS!!!

BIOS Settings are not on any Drives.

Are you still having voltage issues you think are RAID related? If so please explain because this is not possible, so I will let you know what is causing whatever you are seeing as a voltage/RAID issue

I've tried to run the 10 multi with 450 FSB and the temps were a little on the warm side for 24/7 use. I backed it down to 9.5 multi and temps are good for 24/7 use and very stable. I ran LinX last night to verify my RIG is still stable. "GOOD to GO" I'm very busy at work at the moment - but when I get a chance I'll check out the 10 multi 450 FSB and get back with you. Here's the results of last nights test...

Re: GA-EP45-UD3P, E8600 overclock problems

I think Ive mentioned this before but my theory goes something like this.
Considering an aircooled system
and 45 memory controller hub with ddr2 stick(s)
Maximun memory bandwidth read =9-10gb/s, write/copy 10-11+ gb/s latency in and around 60 ns depending on timings etc.

If you use one stick of say 1gb memory only you might exceed that.

Since were in the "usable pc" world youre going to have at least 2 sticks of ddr2 memory and probly 2x2GB sticks minimum(more sticks ,more strain on the nb and they may not be a binned set of 2,or 4..

Try using that memory bandwidth and latency as your board overclock limiting factors.

Some do have a problem over 450 cpu ref(1800 fsb) some dont.
the board is designed for 1600 fsb np
You have 4 main things to consider(aside from the power drain and communication complexities of 2 gx cards.)

1.all overclocks have to work thru the nb or memory control hub
2. the cpu overclock(supposed to be the best)most decent intel cpu's do 50% overclock on air.
3.the memory overclock.a bit more complex but lets say low timing 800 rated memory can do a 25% overclock.1066 rated memory will do less.
4.the mbrd overclock .Our one will do 25%(1600-2000 fsb ok and more)

It seems (to me) it all comes back to the chipset tho..if you try and force a bandwith in excess of the 45's capabilities,your overclock wont work reliably.
