AMD Phenom X4 9850 Black Edition

[Enoad]

So I recently acquired this processor, AMD Phenom X4 9850 Black Edition base 2.5 GHz.


Now seeing this has an unlocked multiplier i tweaked a bit with AMD Overdrive and I have a small question.

I left the voltage at standard to see how far it would go, and I hit 2.7 GHz stable at the default voltage. @ 2.8 GHz I did a voltage jump to 1.30V, this setting also allowed me to boot at 2.9 GHz. Unfortunately from there on Prime95 was displaying errors. Increasing and decreasing the voltages did not help. The temp at that point rose over 60 Degrees C so I stopped. Now my question is , what cooler should I be using to have it at a maximum of 50-51 Degrees C at 2.9 GHz?

when you are overclocking make sure your processor is not linked with your ram, because when your overclocking your processor you will be overclocking the ram as well. and that will cause instability or won't boot at all.

if it is linked, put it in unlinked mode so it only overclocks your processor.

heat sinks:
Good and cheap

cheap, good, and bulky

just two to take a look at. also make sure there room in your case if your going to get an aftermarket heatsink

hmm . not sure how to unlink it...

[grumpydaddy]

This is a possibility too

although you may need a faster fan

I believe if you are in america it is marketed under a different name....will try to find if you want

I'm from Europe. (tyvm for the help so far). I'm trying to find a method to unlink RAM and Proc on the internet but no luck so far.

What is your Motherboard?

[Enoad]

Gigabyte Ga-m57sli-s4


P.S. If anyone can tell me how to unlink my processor and my RAM PM me or post here , thank you.

Unlink your processor and RAM, do you mean detach it off the motherboard?

[kaganader]

No that does not mean to take them off the motherboard. It is a setting in the Bios. the 3 settings are Linked, Unlinked, and Auto. In linked mode it will as one goes up so will another. Hence if you up the Processor speed the Ram will equivalently go up.

So its best when overclocking to have them in unlinked mode.

[Enoad]

I'll try and find it. I got myself a new motherboard yesterday with an AM2+ socket this time so as soon as re-fit them together I'll try and find that setting in bios.

Wow use a Zalman Heatsink i have a 120mm does great for me a 5.0 and i only get to 31c

I recently purchased a Dell XPS 625 from Dell. Please review specs before helping out.

I am interested in overclocking my processor to a safe, but, enjoyable level. I have read many forums and reviews, a lot of similar results seem to be reached using different settings. I have a lot of information and suggestions I need help consolidating. Hence, I am posting here for help.

From what I have read, the Overdrive soft ware is nice, but has the potential to cause problems. Majority says to just do it in BIOS. I am willing to overclock in BIOS, but, since this is my first time, I want to get the method eaxctly right before I do it.

Heres what I knoe so far.

1. I can get 2.8 with a multiplier of 13 - 14, v=stock - 1.4, and possible bus speed increase from 200. The values I have found vary.
2. I can get speeds higher, but, for personal reasons I would nt want to go above 3GHz. Ill do 2.9 or 3.0 only if I'm convinced that its possible with the right steps.
3. Cooling shouls be fine, so no worry there.
4. I have gathered that there is alot more you could adjust in the BIOS. What and where??
5. I have seen changes to CL, tRCR, tRP, tRAS, tRC, etc..
6. Also, I have read it is neccesary to unlink RAM from clocking by ungagnging and setting HT mutiplier to 4x.
7. Lastly, I have read you should overclock up in steps or incrimetns, like, raise multiplier by .5 each time and go up in 3's for something I dont know??

I would appreciate any suggestions, I understand each cpou is different, so results may vary. I need a solid step by step approach and the correct values and incrimets to set in BIOS. I want to keep the adjustments simple and safe, I can handle the BIOS, again, I need to know what to adjust ansd to what value.

I appreciate all your help and suggestions. Please feel free to ask questions. I will respond and provide info the best I can.
