I am a total noob to OC. I am able to run my crappy EVGA NF-41 + Opty 165 at these 2 configs

http://valid.x86-secret.com/show_oc.php?id=155853

CPU 2421.49MHz
FSB 269.05MHz
HT 1076.2MHz
RAM 173MHz



http://valid.x86-secret.com/show_oc.php?id=155860

CPU 2528.57MHz
FSB 280.95MHz
HT 842.9MHz
RAM 180.6MHz


Question is, would I be better off with the higher clock speed (only by like 107MHz) or am I better off with the higher HT speed (1076.2MHz vs 842MHz)? Or is RAM clock also important, although there is only like 7 x2 MHz difference?

CPU speed beats all other factors. I think I saw some benchies doing HT x2 (400) and performed very similar to HT=1000. I'm no engineer but it has something to do with all that bandwidth not being needed on a gaming/workstation type of platform.

Your second combination should be best. Read the following:

This article has done a lot for a lot of people, myself included.

Edit: I just looked at your links, and loosen up those memory timings! You could probably squeeze a fair amount more if you tried 3-4-4-8 or so. Once you've found your highest OC then you can try to tighten them up a bit. Again, CPU speed is king.

CPU speeds is the king - it is the Holy Grail of computing

Definately drop the HT speed, anything above 300Mhz or so on it does nothing for performance on single-socket PCs.

Well, tried to get more out of it and nothing works, I guess I hit the limit of the mb. Thanx everyone.

Well, tempt murphy too much and you are gonna pay the piper. After much mucking around, I think I managed to kill the machine. It won't post. Still trying to figure out which part is toast but post code points to video card. Never heard of OCing cpu frying video cards...

Further update, looks like it is not video. I tried another pcie card to no avail. Nor did a pci video card. I guess mobo is goner. Time to call evga...

I'm assuming you manually cleared CMOS and set everything back to defaults?

You shouldn't have fried anything within the voltage limits you were posting. That's why I have to ask...

Unplug everything, clear the CMOS - remove motherboard battery, change jumper to CLEAR position, wait a few minutes (or if you're like me, 30 seconds), then replace the jumper, and finally put the battery back in. Then plug everything else back in and start it up. That should set you right.

^ What they said, but also disconnect all extra cards, extra ram, all drives, etc. Start with 1 ram stick, the cpu, the video card, the psu, and nothing else. Even disconnect the usb headers/etc. That will make it pretty easy to narrow your problem down to the mobo itself.

I have tried resetting the bios (overnight) by setting the clear bios jumper. I did remove power, but not the battery. Tried unhooking all hdd, nothing. I don't see how 1 stick of ram can post, since it is 64bit and requires 2x32bit stick. Tried sticking different memory in and nothing.
I did not increase voltage. I did try to push htt and I think that did it. my theory is the bios is a bit confused. I guess I can try the battery. Thanx. Will report back when I get home to try this.

Where did you get this piece of misinformation: you're no longer in the era of paired RD-RAM or SIMMs. Your DIMMs are perfectly capable of running in single channel mode with a single stick of RAM.

Err no. DIMMs are individually 64-bit and can be run in a 128-bit dual channel mode. They will still post fine with one stick.

Good news boys, yanking the battery helped. And here I thought the jumper would clear it. So why do they even need the jumper? Just tell people to yank the battery...

Thank you everyone for your help.


The sucker is running in config 2, nice and stable.

p.s.

For the life of me, I don't know how I didn't pick up the change from sdr to ddr also involved going to 64bit memory. I thought DDR was just the rise and falling edge thing. Never thought it was 64bit...

Is it a good excuse that prior to this machine, I was on an Athlon 700? :)
