I recently bought the Opteron 170 from NewEgg for $115.. I currently have it OC'd at 10x at 250Ht for 2.5

It's on a DFI LanParty UT NF4 SLi-DR board

I'm using a Zalman CNPS7000-AlCu HSF and my idle temp is 39-41c and max load temp during a tmpgenc encode is 55-57c

I do batch encodes every now and then, can one of the OC'ing Seniors tell me if I should be worried about the 55-57c temp range while encoding for prolonged periods?

thx

Well, your idle temps are kinda high to be honest. I have the 185 at 3.13 and my idle temps are right around 30c for both cores. They hit the upper 40-mid 50s at load, but that's still within spec.

I started burnin' in a 165 today at 2655mhz with stock HSF and haven't been above 51C. Been running orthos for over 12 hours now . . .

I even ran Premiere, Photoshop, Photopaint, Corel Capture, CPUz, SpeedFan and played the game Red Faction for ten minutes with orthos runnin' - and the core temp went down to 46C.

I'm thinking I possibly didn't apply enough silicon when installing the heatsink, from what I'm gathering, I'm not an avid user of speedfan, but Temp 1 (which I'm assuming is Core 1) runs steady around 37-41c, then Core (assuming it's Core 2) runs steady at 30-34c

I've come to this theory from using CoreTemp and matching the resulting temps of each core. Although if I let CoreTemp run for more than 5min regardless or clock speed (even stock) it shuts my pc down w/o notice.

I'm not familiar with how to post pictures into here or I would display a pic of my results.

As well i've noticed I get these temps whether I'm at 2.0Ghz / 2.25Ghz / or 2.5Ghz

Any feedback appreciated, thx!

OK here is what I get...



Can anyone help translate.. which is which. Thx!

Open your case. Your temps will drop a lot.

My Opty 170 is running at 2.5ghz also and I idle at 41c. Under load I'm in the low 50's with a Zalman CU-7700 on AS-5 in a full tower Acer HX-06 steel case with no side fan. I'm feeding it 1.38v also. Another 4200 I just built with an Opteron 170 cooler acts the exact same way. 38c idle and 50c
under load. Now, it takes a while for everything to mate so I'd wait and see what happens but if you stay under 60c I really wouldn't worry. I have my threshold at 70c. :wink:

It should not take more than a dab of AS5 the size of a rice grain.

I'm not familiar with the DFI mobo but my MSI is a bear with RAM. I only point this out because I noted your RAM clocked at 208 which effectively is a bus speed of 416. That may be causing part of your shut-down problem . . .
June 22, 2007 5:27:27 AM

The restarting thing happened actually at lower clock speeds (e.g. 2.0Ghz / 2.25Ghz both with ram clocks under 200) and only while running CoreTemp.
I can run 2.5Ghz with the 208 Ram Clock overnight w/o a shutdown so long as I dont run CoreTemp.

Although I'm open to any suggestions on how to drop the ram clock spd while maintaining the 2.5Ghz?

I can drop the cpu bus down from 250 to 240 and that gives a 940-960 HT Link and sets the ram clock at 200 but still only achieves 2.4Ghz

Any suggestions on some ideal settings? I'm not looking to intensely over clock this opteron, just want to squeeze a little more out for the money.

I use the DFI Expert boards and Optron 146's in CM Stacker TO-1 cases with Thermalright SI-120 coolers.
At idle 2C and after an hour of SuperPi/OCCT 13C over room temps.

Everything is at stock volts and a 950Mhz OC on the CPU.

I bet if you use Smart Guardian to check your temps it miay show just a bit lower than Speed fan.

With you using dual cores you will run a bit warmer but ONLY when doing something that pushs both cores close to the max.

Also you should be running the RAM in T1/CR1 mode not T2 like an Intel....it's an Optron so take advantage of it.

If you need any help in setting the RAM up ask R.Gone or Angry Games on the DFI (DYI) Street forums.

I took a quick glance through the manual so insert a standard disclaimer here. :) 

Under PC Health Status in the BIOS verify the Shutdown Temperature. Could this be part of your problem?

Under Genie BIOS Setting check the DRAM Frequency Set (Mhz) clock limit. When OCing you need to manage your RAM settings with a 'memory divider' or similar setting with the goal of keeping it as close to stock speed as possible. In the case of a 300MHz fsb you would need a 2/3 divider (2/3 x 300 = 200 ( x 2 = PC3200)). This setting may be a key to your OC. Verify so that it does not create a problem for you.

Set the PCI eXpress Frequency to 100MHz.

The 170 has a multiplier of 10 - with your HT set at 3X You should be able to set the FSB Bus Frequency WAY above 250MHz. If the other settings are properly managed you should easily be in the 280-290 range - if not higher with proper cooling.

OK.. I took ZOldDude's advice about 1T timing and it locks me up everytime. I have to stay on 2T

I also took WiseCrackers advice and tweaked it a lil' (FSB 250 | HT x4 instead of 3 | 2/3 divider) and got these results..



Does this look better from previous results and more so what I'm aiming for?
Does the lower Ram Freq and Lower Timings make a bigger difference?

Thanks

** Under a full system load I'm maxing 49-51c max on both cores **

The ram freq is looking much better but your timings are looking pretty tight. Compare to the *SPD* settings and stay *loose* until you reach the cpu bus speed that you want. Then you can tighten them up a bit . . .

Bump your HT back to 3X after you loosen the memory timings a bit and start working your way up from cpu 250 fsb. It looks like your current RAM freq will let you approach cpu fsb of 295-300 before the RAM freq passes 200 (which is perfect!)

10 x cpu FSB 295-300 would be 2950-3000GHz. Dang near a 50% overclock! Sweeeeeet . . . :D 

The best advice I can give you is to work a spread sheet with all the math. In theory with a 3X HT and 10x multi you could go 333 cpu fsb before your HT got above 1000. That would take some work (and serious volts and cooling!)

What was neat about that DFI was the CMOS reload. That is some good stuff, there . . .

Good luck!
