Finally broke through a roadblock on my AMD 955

Ya man right now I have my cpuNB VID set to 1.200 and running the frequency at 2600. Try dropping it down little by little and see if that may help with temp.
 
I'm really quite surprised you need that much cpuNB VID for your 955BE. Those chips seem to OC with less voltage than the 940BE (as they should since the process is older). Can't get a stable 2400 MHz at ~1.225 cpuNB VID? It would sure help the temps if you could. ;)


Also, if you don't mind my asking, what SETI username do you have ...?

User name is: Jack Reeves

I'll try lowering the cpuNB voltage and see if I get a lower temp with that.
 
you should try the settings in my post, Treckins 4ghz bleh bleh bleh, its on top of the stack right now.

Try you SB to 1.35, I SWEAR if that does not fix it :p

Also, judging by your temps, I would guess you need to reseat your CPU.

At those voltages I load at no more then 43. Right now I have it a 1.5875 in the bios and it loads at about 59.

I do have the Zalman 9900 instead of the 9700, but I dont thing that is 10C alone.

Def try raising your ram voltage to 1.60 - 1.64.

My GSkill Ripjaws 1600 9-9-9-24 runs completely stable at 1666 8-8-8-24

EDIT: What are you running on the actual NB? Raising that from 1.2 (assuming 790fx chipset) to 1.28 made mine more stable for sure.
 
Here's all my current data for working at 3.7. I don't understand how reseating the CPU is going to help though. When I installed it (Not my first one either :) ) it slid right in with no pressure. I did reseat the Zalman though, and reapplied thermal grease (Zalman's brand) to no effect.

That's looking good!

I'm sure it's the heatsink that's stopping you. Those older styles just don't do well on the modern CPUs. A vertical tower is what you need. Pretty sure your HAF922 can accommodate a 120mm version ... :)

Any suggestions :)

Price is a factor, would like to keep it below the wife's radar. :chair:

I can get a Mugen 2 on Amazon for 49.95 with free shipping and no tax. From what I've seen here, http://benchmarkreviews.com/index.p...k=view&id=436&Itemid=46&limit=1&limitstart=12 it shows that it scored top marks against the rest of the field.

There are several good options and I'll list them in ascending order by price so you can stop when you start coming out of the weeds. ;)

$35 http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
$40 http://www.newegg.com/Product/Product.aspx?Item=N82E16835207004
$59 http://www.sidewindercomputers.com/thulbledrec.html

But there's a catch with the last one - it doesn't come with fans. If you have your own that makes it easy but I'll list some fan options just in case. You can run one or two fans and the push/pull will help but won't double your cooling. I'd run two with the first choice - the others are second fan optional.

Cheap but good

Dude I'm almost 100% positive you dont need to buy a cooler yet. Have you tried the voltage settings I suggested earlier? You should be able to lower the vcore if the NB/SB voltages are holding you back.

Also, I have my ram multiplier down one tick, so that that I can run I higher ref. clock w/o expensive ram. you could easily use less voltage or at least make less heat at that same speed if you used 250 x 15 instead of 200x18.5.

I definitely tried those multiplier settings and I settled on a higher ref. clock and lower (well, I run 250x16 :rock: ) because those high multiplier settings were making my max temps hit close to 70c.

I was going to ask you about your HT settings as well. Have you tried setting 2500nb/2500ht? This may only be available to me because I am running a higher ref. clock, and thus you would have to raise the nb/ht multiplier past stock.

^ this is another reason to prefer ref. clock overclock over multiplier overclock.

Best of luck :thup:

EDIT: When I said 'reseat the cpu' I meant the thermal past cleaned off w/ rubbing alcohol and then use a bit more then most people tell you to. But yeah, you say you did that so NM. I was just surprised at your temps/voltage settings. at that voltage, I wouldn't get into the 40's, and as I said, we have almost the same cooler.

I haven't yet because I've paused the OC process to go ahead and clone my hard drive. Transferred to a 1tb I stripped from a NAS whose controller board went bad from a 320g with a smaller cache and slower spin rate.

Otherwise, I've been hesitant to start because when I went to your other thread, I noticed your screenshots didn't reflect full load. I'll do some incremental change this evening after I put my 5 year old walking distraction to bed (my daughter). Just need to find time to concentrate.

I do want to better cooler though. My case can fit a Mugen 2 and man that thing can really keep the 955 chilled.

I noticed that as well. Temps don't count for much at idle. ;)


Kids are wonderful but it's MUCH nicer when the grandkids are that age or older ... :)
 
Oh haha ill post now in an edit ;)

EDIT:

Furmark MultiGPU + Prime95.

This is a short run, ill do more testing and post it to my thread (Treckins daily 4ghz OC).

Just Prime (also a short run).

Thanks for those screenshots, I'll be running some tests this evening to see if I can get some improvements by utilizing your data.

Oh, and I just found a problem that may have been preventing me from getting good temps. The front 20cm fan on my HAF 922 was jammed by a 4 pin molex connector I hadn't noticed. This must have happened after I installed the new Corsair. I love the power supply and its stats, but really wished it was modular. Ah well, had to balance budget with quality, and this is what worked.
 
Well, I've got my CPU NB at 2600Mhz and 1.1875, it crashes any lower than that. Now let's see what's next.
 
Temperature is under control at 3.8. I can't believe it. It's not spiraling to 60, but sitting nice n' cool at 54c while running prime 95.

CPU NB 2600Mhz @ 1.1875v & CPU V @ 1.425.

Now to run 95 for the night and see what happens.

Here's a screenshot of all my numbers.

Crashed after about an hour of Prime 95. Should I increase my CPU NB to 1.2? I can tell I'm close, problem is I don't want to go too much higher in temp than the 56c it would hit every now and again.
