    Default E8400 and UD3R help to 4ghz

    I can't get my UD3R and E8400 up to a stable 4ghz. I'm afraid to keep messing because I don't want to damage something.

    3.6ghz is stable on the following:

    If I try to change to 445mhz it will boot and seem to run fine but running prime95 stress test causes the system to reboot itself. Temps are not an issue as I have yet to see the chip go over 53C. I'll just be honest.. I'm new to overclocking and I don't understand all of the different settings.. like I don't know what "drive strength" is or the "MCH" stuff. There seems to be a lot of information on how to set things and not a lot of "what exactly am I messing with and why".

    I've just spent the last hour trying to get thing stable and I give up. I read your thread and played with the voltage, drive strength, static tRead and MCH and I'm still unable to run prime95 for more than maybe 10minutes without a restart.

    As far as I've read I should really need to increase anything past that, and I'm afraid if my system reboots itself anymore I'm going to end up damaging something. Thanks for trying to help but I guess I didn't get a very good draw on something.

    How much and what kind of memory are you using?
    You may try your static tread value from 9 to 10.

    If your default voltage for your cpu or vid is 1.25v, you probably need more than 1.2625v to get to 4ghz.

    Good luck.

    Default voltage is 1.225 for an E8400 3.6 is stable at 1.25v. Maybe I do just need more voltage.. what's the likelihood that hours worth of rebooting is going to hurt something? It's not like 3.6ghz is bad..

    I have 2gb of 800mhz 4-4-4-12. Specifically: Newegg.com - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400PHU2-2GBHZ - Desktop Memory I know it can run forever at 951mhz 4-4-4-12 so I don't think RAM is the problem.

    Try using less agressive memory timings for 890MHz. Use 5-5-5-15 instead of 4-4-4-12. After you get you setup stable, you can try decreasing those. Remember, one change at a time then testing.

    Default Re: E8400 and UD3R help to 4ghz

    Just to give you an idea, my first E8400 has a vid of 1.20v and I needed vcore of 1.2625v to get stable at 445x9. Dan's chip has a vid of 1.275v and he needed 1.30625v to get to 500x8 but he is running at a more taxing higher fsb even though it is at the same overall clock speed of 4ghz. So if your vid is 1.225v, which is between mine and Dan's, then you likely may need a vcore between 1.2625v-1.30625v, YMMV.

    More Vcore may be needed. Also lowering MCH ref by one or two notches while CPU Term is at 1.2V, then returning CPU Term to its previous value may help. Also trying higher and lower MCH voltage and PLL up to 1.61V can help.

    As a side note, 1.225V is not the default voltage for all E8400's. Every single chip is individualy given its own VID. The VID coresponds to the value Intel think it should be run at to reliably give stock speeds. I've seen VIDs on the same chips range from 1.1325V up to 1.2625V. The lower your VID, possibly the higher you'll be able to overclock, or you may reach the max overclock with less voltage than someone with a higher VID.

    I'm really sure the RAM is okay. It passed memtest at 951mhz and I've been running it at 951mhz 4-4-4-12 for 2 months, so a decrease to 890mhz should not logically cause problems.

    I think I might actually be stable.. Prime95 has been running about 20min so *fingers crosses* Only thing I did was increase voltage to 1.31875 and termination to 1.26. Temps are now up 4 degrees on average but I still run about 41-58C (58C being what it is now at while prime95 is running). I might be able to turn other things down now that I know i wasn't giving enough voltage. If this passes I'll play with things some more.

    How does one determine an individual chip's VID?
