Yes! They are exact same thing. The "GO" or normally called Stress Prime is the window interface of mersenne.org Prime95 that allow you to see the clock speed at which you prime and time(how long has elapsed). I will trust this than the usuall Prime95 interface that doesn't provide any such information. You could prime at stock speed and then use clockgen to OC and claim it's stable at the OC speed with the usuall Prime95 interface. The Stress Prime will not even show your clockgen speed, except you set your OC in the BIOS.

Hi guys,
do you think that 2870 at 1.65 vcore is good for a 3700+ San Diego? It's doing Super pi 32M (Does It imply the cpu to be Stable? I don't know, I don't have cpu in my hands to test it.. :( )
Watercooling I precise. Not box cooling.

Yup that’s pretty good for h20 cooling. Mine does 2800 at 1.65v. SuperPI is a start for a stability test however I wouldn't trust a run or two of 32 to be stable.

I just ordered a 3700 SD , I have a few questions

1. Cold bug? using vapochill LS
2. I see people getting 3.1 gighertz or even 3.3 gighertz on this CPU with some GSKILL.
What is the average OC with my setup
thanks

I am getting 2.94 GHz on air with 1.75V.
So it is possible to fly high, it all depends on cooling. With average cooling you should expect 2.8 GHz with 1.5-1.6 GHz. Anything better is with a grace of overclocking god.
Stability is a different issue.

heh yeh i bet you arent 24 hour prime stable at 2.94ghz lol

just amazes me sometimes...hell my max screen is like 3.2 or 3.3...but i dont post that as my overclock lol...

its gatta be atleast pi 1m stable imo to be important unless you are showing and label it as "max screen"

Has anyone got the TPAW version rather than the SPMW ones yet?

I've not yet bought an SD-3700 so would like to see if there's much OC difference between the two (although I'm not holding my breath for staggering difference :) )

I've contacted some stores that have confirmed they have the TPAW ones so sourcing one won't be an issue for me.

Even with 1.7 volts, I can't get above 2710mhz prime'able. I MIGHT be able to get some more out of it with more volts, but it's at the point of diminishing returns already. A little disappointing, but not at all surprising.

More than likely heat is preventing you from getting it higher, check your cpu temperature and if you're running on air, I wouldn't put more than 1.66v for 24/7 use. Dropping the vcore might actually help you stabilize 2.7Ghz, try somewhere around 1.50~1.62v for 2.7Ghz.

That's not NICE. My chip will boot at 2700MHz with just 1.4V and run 32M super pi without any hitch. It fail prime at that voltage after sometime, but with 1.5V prime run all day, just have to terminate it after 15Hours.

Mine starts needing more vcore at 2.7Ghz (about 1.5v). Its fairly stable at 2.81Ghz but with 1.67v. It ran prime for 1hr18min before I stopped it. I'm running some burn in programs and will try 1.65v prime for hopefully a longer time. If that is successful I'll try 1.625v. Currently prime around 20 minutes at 1.65v.

Thanks agenda2005.

Unfortunately, I can't really dismiss user error at this point. Last night I was trying to find the lowest voltage that I need to run ~2700mhz with a 10x and 11x multiplier, and I came back to 1.6v.

Just for the hell of it though, I decided to give 8x337 and 9x300 a try. At 1.5v, both error in prime almost instantly. Being the impatient person that I am, I bumped the voltage up to 1.55v, and tried 8x337 again. It's running happily so far, although it's only been running for under 30 minutes. If it runs for a couple hours, I'll try for a bit more speed at the same voltage, and see what happens.

Temps shouldn't be an issue, since I haven't seen anything over 45C so far. 43C seems to be about a normal load, spiking up to 45C for a second or two every so often.

Edit: 8x337 at 1.55v failed prime after 2 hours 41 minutes.

1. Sorta. I've heard stories and I have an SD3700 with cold bug. There is a good chance my Sandy is generally defective though. So my cold bug experience might be due to a defective processor.

Cooling : XP-90C with 92mm 38T Vantec Tornado at 5100RPM.

45°C at 1.71v on air?

I havent that at 1.4v stock :D

2.8GHz 1.4v = 50-51°C

GJ Dread, you don't see many posting 25 hour Prime stable OCs.

Memory is the main limitation, I mean memory controller.
If I run my Winbond BH-5 at 220-230 2-2-2-5-1 then I get to 2.92-4 GHz with this SD 3700. But ... if I run it at 260 at 2-2-2-5-1 then I get max to about 2.85-86 GHz 32 MB SuperPi stable. This is all on air.
As if there was some magic ceiling for the bandwidth. But of course this is much better than Winchester chips.

I`m at about the same place with my SD3700 and OCZ PC3200 EL Gold kit.
257MHz CAS2-2-2-6 1T @ 2.6v DFI NF4 Ultra SuperPi and MemTest86 stabile.

i've noticed the same thing with utt. i've also noticed that the rig gets unstable when htt is ~300. as to whether it's cpu, mobo or memory, i'm pretty sure it's the dfi. here's why:

SD3700, twinmos utt 5:6 divider (runs at 228 when fsb is 290). this memory is stable 2226 timings @ 250 3.2v. when i put on the divider and run the memory slower, i crash when i near 300.

SD3700, gskill tccd, 1:1 divider. completely and abruptly unstable at 300htt.

i have tried changing volts on ldt, chipset without luck, just can't seem to get >300ht stable. and yes, ldt is set to 3x.

You might wanna factor in the ambient temps, high speed rev fan 5100 RPM WOW! or could be a bad MB sensor altogether.

DOES anyone here living in Atlanta knows whether Monach allows you to hand pick a CPU if you walk into the store?

Most stores will, call Monarch and ask. The OEM CPU's come to them in these plastic trays, I wouldn't see why they wouldn't let you pick from the tray. That's what my local store does.
