Q6600 OC Testing

post #1 of 8
Thread Starter 
I got a new toy from our Intel rep on Saturday, a nice Q6600. This is going to be used for demos for some business clients of ours. Naturally, I had to do some OC testing first

Motherboard: Asus P5K Deluxe
CPU: Q6600 B3 Stepping (L640F)
Memory: "Value" 4Gb Kit
Cooling: Thermalright Ultra-120 Extreme


Ambient Temps: 25 C
Idle Temp: 31 C
Load Temp: 49 C


Current Speed: 3.156 Ghz
FSB: 351 Mhz

Dual Orthos stable, run for 10 hours last night (screen shot from this morning though). Not too bad so far - it's not running quite as hot as I'd imagined.

my validation is in my sig.

Motherboard: Asus P5K
CPU: Q6600 B3 Stepping (L712A)
Memory: 2g HZ kit
Cooling: Tuniq tower120+ shin-etsu`

3ghz, 7x multi @ 430mhz FSB, 1.28vcore.
RAM- ~1040mhz @ 4-4-4-12-4-20-8-9-9-9, 2.3v

ambients- 26c
idle- 36c
load with Superpi 8mill and SiSandra CPU bench- 43c
load w/ TAT- 51c
------------------------
the tuniq is working surprisingly well on the Q4. I am hoping to hit a 3.2-3.4ghz OC near ~500mhz FSB.

*off topic..kinda..

I used SiSandra to test the cpu performance in a couple of different tests. The CPU Cache and Memory benchmark, worried me some.

When I first ran the test, at stock FSB, clocks..the graph showed my cpu performing well below a 'regular' Q6600, in terms of cache throughput speeds. Since everything was still set to stock, I assumed this was due to the NB latency at the 266mhz speed. So far, I have not noticed a reset in the NB strap...even at 430mhz FSB. The only time the mobo has had a reset, was for mem dividers.

Can you run the test yourself, and see if you experience the same phenom?

Here is why I am confused:

CpuZ latency test, w/ cpu and mobo at stock settings, measured out at L1-3 and L2-14, but this combination scored the lowest on the SiSandra CPU cache benchmark...almost 5K below the listed specs for a Q6600.
At 430mhz, CpuZ latency test w/ cpu at 7x and mobo at 430mhz, measured out at L1-4 and L2-18...yet here I am 3-5K above the listed specs for a Q6600...?

any insight?

sure, I'll give it a test today and see what I can come up with.

Hey nice one there tankguys! I have the same stepping, what is your VID? You can find it in coretemp, mine is 1.2625V.

I don't think AI Suite reads the core temperature, I think it reads the Tcase (CPU temperature). Try using coretemp 0.94 or TAT to get a reading of the core temperatures, also SpeedFans core temperature seems to read 15C too low. You might find your temperatures are a little higher than you think.

@ CL3P20

If I'm reading you correctly, you're scoring lower than expected at stock speed, but everything is ok when overclocked? Could speedstep have been turned on at default settings (thats what happened to me when I went back to default settings to test this)? I don't know squat about CPU-Z latency test, so I can't say much about that.

This is what my results were at stock speed and memory set by SPD (800 MHz , 5-5-5-18). BOINC was running in the background on both tests so load was already at 100%.



And this is at 3200 MHz (356 x 9, 1068 Mhz, 5-5-4-9)



I received the same results in the CPU-Z latency test at both stock and overclocked, and the Sandra results looked to be on par.

Speedstep is my only guess
24/7 BOINC!!

That shows your still in the same FSB strap..which is good, the latency is lower at your current strap.

The first graph you showed is what I expected to see when i tested my cpu...but my 'curve' was around 19,000mbs, instead of 22,000ish.
Oh well...~55,000MIPS now at 3.2ghz! Hehe, I cant wait for my new vid card to get here! Rise of Legends on Full Q @ 1680x1050, here I come! I feel bad for my e6700/p5b now..lol.

Very possibly. However, coretemp doesn't seem to work in Vista x64, so no dice there. I will likely create a vmware XP image, however, so I can still use some old software that doesn't play nice with Vista... in which case, I'll see if coretemp will work therein.
