Have you tried overclocking the cpu with the ram set to unlinked?

The ram can definitely hold back the cpu if they are being jointly overclocked.

I have the same ram (OCZ SLI PC8500) and using the latest 0903 BIOS. I think have noticed the same performance benefit you describe running the ram at a lower speed. But I just want to confirm because it still seems really strange.

I am running an e6300 Rev L2 at 7x1840. My OCZ ram is stable at 4-4-4-10-1T @ 1066mhz yet most of my Everest Memory tests show the same 4-4-4-10-1T timings at 920mhz to be quite a bit faster, especially the Memory Read(~9990 vs. 9100). The only change is the memory speed. Is this the same phenomenon you were describing or did you have slower timings at higher the MHZ. Thanks

Yup have them set to unlinked. FSB is set to 1400 currently. I tried 25 increments and would immediately lock up when i try past 9x350. PC would not POST or if it did i would get BSOD during vista startup. Have not even touched the memory yet. I also do not feel safe bringing up Vcore to high.

This memory seem to be great if you want to work at advertised specs butnot that good of a overcclocker. Again this is only speculation so far about the memory. Could be something else that i am over looking.

I have never been a fan of Patriot (had two pairs in the past with poor performance). The thing is the best overclocking ram for this board is anything with Micron D9's. The Patriots are using Infineon IC's. As you suggested correctly, they are decent at stock but not strong overclockers.

Yes that is correct. 1T timings are much faster than 2T almost regardless of clock speeds. I tried the ram both ways and 1T @ 800MHZ with tight timings (I run 4-4-4-8) is faster than 1066 at 2T regardless of timings.

BTW 460 FSB on an E6300 is very nice. You should be able to get close to 500 FSB if you put some kind of active cooling on the nb/sb.

Stable at 2925MHz

Next question...to quote you: "You may have to up vcore to 1.4 for 350-375"...how do you determine if you need to up the vcore when you hit 350??

Run orthos,if fail then is time to raise the volts.And that screen don't mean you are stable.Run orthos for @ least 1 hr.If is no stable going to fail fast.This is the screen you need to be sure your oc is stable or not.

**Robilar** · 03-21-07

Right Alex. Orthos will push your cpu to its limit. If it doesn't crash and your temps are reasonable you should be fine.

dijonace · 03-21-07

Thanks for the reply. Ran the orthos beta test for just over an hour. Zero errors. Maximum CPU temperature I saw was 48 degrees C during the 8K test.

I just took a look at PC probe after the test was done and saw a red section for the CPU VTT at 1.62.

Should I make a change to my voltage?

Right now my voltage settings in the BIOS are at:

1.35V
Auto
Auto
Auto
Auto
1.55V
Auto

Robilar...I've seen your settings on image #6 where you have them at 1.53125, 2.25, 1.30, etc but I wasn't sure if I should go down that path yet until I hit 350fsb.

If you provide a quick summary here of your issues with the Asus P5N32-E board, I may be able to assist you.

Your pictures show the Asus board so you can see the confusion.

the ram btw, should go in the two blue slots (or two white slots)

Your cpu fan should be oriented to blow air out of the back of the case

The cpu fan header should use the bottom (or right) 3 pins so that it locks on the tab supplied.

Edit, ok clicked on your newegg link and saw that you got an evga card.

So your assumption is that the card is defective or the board?

If there was a broken memory clip out of the box, you may have gotten a returned board (not new) and possibly defective. Shipping would not break a memory clip.

C2D E6400
EVGA 7600GT
Asus P5N32-E Plus
Crucial Ballistix 2x512 MB PC-2 6400
Apevia 600W Power Supply

Are these specs correct? (You should fill out your system specs, it took me awhile of jumping around the pages of your log to figure out what you actually bought)

robilar i updated my system info for ya. those specs are correct just decided to get the c2d e6300 instead. i have sent the motherboard back and video card back today. how can i determing if the memory goes into the 2 blue or 2 white what is the difference? i noticed the 2 white slots were easier to get the ram in rather than the 2 blue but that could have also been from the broken clips cause it was the 2 blue's that were broke already. i have my tuniq blowing towards the rear of the case with 2 fans blowing out the back right in back of that, 1 top fan blowing outward and 1 fan in front blowing in. should i add more if so what size and where and which way should they blow? what other coolers if any would u recommend i get?
