Ok everyone-I dont know what the deal is. I have my Phenom II 720 at 16.5x-HT at 218-volts at 1.392-Running prime my temps dont go over 45c according to HWmonitor but i am still crashing after about 20 minutes. I have upped my volts all the way to 1.425 and still dont go over 49-50c but it still crashes. Could this be a PSU problem ? I have the Ultra 650- It just doesnt seem like i am pushing too hard so i cant figure out why i ant get stable. Can anyone help me or offer some advice. If any more info is needed please ask-i dont get offended easy so dont be scared-LOL

I have read that too-so just try the smallest tick and go from there ? I have EPP on, and i think i can tell it to adjust voltage too. I will try and let you know. Thank you for the idea.

The Platinums I see at NewEgg are rared at 2.2v (dont' go that high if you don't need to), unless your running the 1150s, which are 1.8v. You may also want to loosen your timings until you find what your CPU is capable of, then go back and start cranking your memory timings down.

PS: Be prepared to reset the CMOS when you tighten them back down!
 
Relax the timings to 5-5-5-15 or even 6-6-6-18. Get your CPU overclock stable first. Keep in mind that you may not be running your core voltage high enough.

Optimize your memory after you have reached a stable CPU overclock.

I am running Core2 systems so I do not have a good feel for AMD systems.

Try upping your voltage more. With your FSB and multiplier, you are around 3.6 GHz which is pretty high. Some 720s OC better than others, try increasing the voltage more to stabilize that OC. For your reference it took me 1.45 V at 3.64 GHz.
 
I have the exact same ram in my AMD rig at 5-5-5-15-26-2T 2.1 volts and it is stable as a rock....

IMO if you have played with all these timings and still crash you might have a bad stick or two....

i have ran memtest 100% coverage and says no errors. I am gonna start over from the beginning-stock everything and go from there again-cpu first then maybe a little bit with the ram-

Hi, :hello:

I had the same problem it was the RAM 1.8volts resolved the lockups...this is the email I received from OCZ tech support.

Description: OCZ3P13334GK

Please be advised that the status on your trouble ticket
has been changed from Acknowledged to Waiting on Customer
with the following comment:
-------------------------------------------------------
Comment: Hello James,

Try clearing the CMOS and then manually adjusting the memory settings in the BIOS. For this particular kit I recommend using timings of 7-7-7-20, command rate of 2t, and 1.8 volts.

If the problems persist even with these settings try testing each memory stick individually with Memtest. You can download a bootable copy from http://www.ocztechnologyforum.com/forum/be_pagegen.php?id=tools

If you find errors with your memory, especially if the errors follow one particular memory stick, your memory is likely faulty and will need replacement with an RMA.

I am now stable at 17x multiplier-215Ht-1.41volts-which puts me at 3.65Mhz. Ran OCCT for 3 hours and then Prime for 12. I havent touched the memory yet-i think i will just try turning on EPP and see what happens first then go from there. Thanks everyone .
 


Yes Sir, then once EPP is enabled and you lower you timings you should get a higher overclock... [:lectrocrew:6]

So can you help me understand why EPP would help me get a better OC? EPP puts timings at 4-4-3-15 at 2.1 volts-i put them at 4-4-4-15 at 2.1 volts-can i lower my cpu volts now and try stressing it or is there better ways to get a little more ?
 
If you open cpu-z, you will see a tab called EPP in the timings table....you can try those timing and go from there, they do not have to be exactly as they appear on the EPP tab but it should give you better timings....as opposed to the other tabs on the left hand side....

ok-i see what you are talking about-i actually have it set to 4-4-4-15 with the EPP handling the voltage-so i am assuming my ram voltage is at 2.1-i just ran 2 hrs. of OCCT at 3.65Mhz.----- 17x-215 bus-NB+0.050 which put it at 1.35 volts-and +0.150 cpu volts which put it at 1.47-cpu never got hotter than 48c-TMPIN1 59c and TMPIN2 49c.-i was thinking that wasnt too bad :)
 
Exactly... see its not that hard...... [:jaydeejohn:5]

You will learn by playing around with your timings, not all motherboards are the same so the best way to make sure you are keeping a safe track of them is to write them down, then later you can compare numbers and find your sweet spot.

Well.......Frustrating but rewarding-my ram is at 860 and some change-gonna work on my Saphire 4830 now-i cant get Rivatuner or ATItools to download though-
 


Why cant you get Rivatuner and Ati tools to work?
