Athlon II X4 620 - AM3 (938) Package - OCing Help

Last response: in Overclocking
Share

I've looked at a bunch of rigs that have overclocked the X4 620 upwards on 4GHZ, however, as I look into their CPU-Zs they all list an AM2+ package, instead of the AM3. I built my rig around July 2010, and overclocked mine to 3.4GHZ, as seems to be common, but can't seem to get it past that point. My setup is as follows:

CPU: Athlon II X4 620
Mobo: MSI 770-G45
RAM: 4GB OCZ 1333MHZ DDR3
Video: XFX 4890
PSU: EarthWatts 650W

I forget the name of the aftermarket HS+Fan I bought, I know twas a CoolerMaster. Prime95s for 24 hours at 41C.




RAM is at 1397MHZ, CPU-Z is telling me it's 1.5V, but i thought twas at 1.67.

I've tried turning down the HT Link, the RAM ratio, increasing/decreasing the voltage on the CPU from 1.35 - 1.5.

Can anyone toss me some advice as to how to push this speed up? Is this my MOBO's hard limit? My CPU's? Am I forgetting to adjust something?

And if people would be so kind, I don't need advice from the Monday morning QBs, or the couch generals. I'd like to hear from OCers, who are at or above this level. :pt1cable:  [Quick edit to this, I do not mean specifically for this chip, what I am referring to is people who have OCed to some deal, and have succeeded at or farther than I have]

I have mine set at 3.5Ghz 100% Stable & Primed 24 hours at 60c.

I'm thinking maybe lower your HT & NB or MCP. Boost their Voltage up too.
You might wanna boost the Voltage on the CPU to 1.55v. Also boost memory to 1.95v cause this stabilizes things on my board.

If that doesn't work try lowering your memory Mhz. It may be too FAST. I am not sure about DDR3 timings but it helps on my board if I lower my MHZ to keep it 50 Mhz near MAX.

Some other minor details to look at.
1. Make sure your NB & MCP is not running over 65c. If that's too hot it can Crash.
2. Is your motherboard running over 35c? The place right under the CPU may be overheating and causing your OC to become unstable. Make sure you have your MB cooled as well.
If MB too hot, get a case that has TOP and side case FANs & reverse the HD fan so it sucks HD temps air out at front.
3. Is your power supply STABLE? Some power supplies are cheap and can the culprit to cause OC failures.
4. Is your RAM sticks pushed all the way in and WELL aligned? This can cause OC failures too.
5. Is the CPU inserted all the way flat down?
6. Is the power plug connected to the MB well connected?

That's everything I can think of.

Look at my settings carefully and try the same exact settings to see if they work for you. Your MB is alot better than mine it should go higher I believe. Mines just an ASROCK $35 board.

Good Luck.

you are never going to hit 4 ghz on that cpu. Its just not made to do so. Even people with water cooling only get to 3.8-3.9 if their lucky. You might be able to get to 3.5-3.6 but that about it.

Here is a great guide on how to oc am3 cpus. http://www.overclockers.com/forums/showthread.php?t=596...

After reading that and if you still need help come on back and well help


After watching all my friends OC their x4 620's I've come to the conclusion that air, water or whatever the NORMAL standard max is @ 3.5 Ghz 100% stable. After that the CPU starts to develop electrical anomalies somewhere and the CPU eventual BSOD even if the TEMP is under 50c. I'm not sure if AMD has the temp diode too far from the actual HEAT element or whatever but it seems to be clear to me that the CPU still fails at 3.8 even though temp shows 45c and that's using dried ICE on a STEEL heat sink so it seems the TEMP almost has no bearing on the outcome of the final MAX Ghz. Next step would be nitrogen but I'm not gonna go that far.

If you think about it though at 35% OC and 100% stable this chip is still very nice for it's price. No complaints from me. To be allowed any higher OC would be way too good & would put Intel out of business:) 

I think these athlon IIx4 chip are the best chips for a budget build by far. you just can not beat the price performance ratio of these things. I am very pleased with my 630. and you are correct all athlon IIx4 seem to top out at about a 36-37% oc and no matter what else you do it will not budge any further. But still I paid $89 for my 630 and I overclocked it to 3.6. Just insane chips for the price.

Here's a trimmed custom Everest report of the computer sensor and overclock at idle.

Questions 3-6 are all answered 'Yes'. At idle, my mobo is running at 30C. Nothing is over 60C.

Good news for we 620 OCers.

I went back into my BIOS and decided, heck, I'll give it a shot on what C had posted earlier. Adjusted the voltages up, and low and behold:

it failed. I wondered back, and remembered a post saying to make sure that you manually set the RAM timings, and I checked mine. It was set to auto. So I set mine to 9-9-9-Auto, boosted my bus to 286 and it loaded! So I went back, played with settings, checked the manufacturer's recommended timings and all, and set mine to 9-9-9-24-30-1T (CL-tRCD-tRP-tRAS-tRC-CR) . I left the voltages at the new settings. Then I pushed up the bus further to 293. That's 3.8 GHZ. Going to Prime95 it. I've done some other attempts at P95s and i've been updating this as I go. The Prime95s are usually crashing within a second.

If this fails, I'm going to use the following timings: 33-107-4-10-5-5 (RC-RFC-RRD-WR-WTR-RTP)



Here's another everest custom trimmed report.
