Spec in sig. I got this processor (it's a venice core by the way) just a few months ago. I have done overclocking before but my knowledge is very limited.
I have (up to yet) got it up to 2300mhz (2.3GHZ). My multiplier is x10 (i have the option to go higher but i never have, is it ok to go higher?
HT link is running at 1GHZ (which i think is wrong, i think it's ment to run at 800mhz)
I have set the memory to auto as i forgot how to work out what to set it at. Anyway CPUZ says it is at 115mhz (i am running pc3200 corsair, i know it's not the best but i can't afford new at the moment)
The processor frequency is at 230 (as you have probably worked out :D)
Finally the processor voltage is at standard (1.2v)


What is the highest temp i can go up to?

Thanks, any help greatly apreciated :D
 
Ok your motherboard is declocking or ram serverly. It should be around 200mhz not 115mhz. In the bios, go to the memory setting and change the divider to 333mhz. that should make your mem run faster.

Second of all amd didnt make a venice 3700+ its a sandiego which means it has a 11x multi.

The HT is surpose to run at 1ghz so your ok with that.
 
I'm assuming this is the Socket 939 San Diego core?

If so, max temp should be about 55C.

HT Link is supposed to be 1Ghz. Having it lower by a couple of hundred mhz won't make a noticeable difference, but having it over 1Ghz can cause problems and instability. If in doubt, go for below 1Ghz.

That RAM will run at DDR400, so as jaykay suggested, use the BIOS to put it on a 333 divider.

Something like CoreTemp will tell you the revision, if it's the E4 then you're likely to get very good overclocks, the E4 silicone was known for its clocking ability. However, if you have the E6 version, it's most likely a Toledo core with one core disabled, and will therefore probably not overclock as well. Even so you should still have no problem getting at least 2.5-2.6Ghz out of it.

The E4's managed anything up to 3.0Ghz; my E4 runs at 2.8Ghz at stock voltage on stock cooling :cool:

I got mine to 2.7 Ghz stable on air (245 Mhz * 11 multiplier) without breaking a sweat. That achieves about 40 C normal and 50 C under load (Coretemp), and vCore at about 1.46 (CPUz).
 
right here is my settings so far:
cpu frequency- 230
multiplier- x11
DDR voltage- auto
processor voltage- +1.20v
HT link speed- 1ghz
memory-


The memory is where i now run into troubles. I have looked everywhere and can't find a memory divider option, i can only find 'memclock value' and that only goes upto 250. I did set it at 166mhz and the system was un-stable, i set it to 200mhz and still un-stable so i just set it to auto and it has loaded.
I am currently at 2530mhz (2.53ghz) how much higher can i go? According to speedfan my core temprature is 21C i presume i can go much higher than this, but how high?
 
I'm not an expert, but 2 things I would suggest:

1. Use Coretemp or TAT for temps. These are more accurate than Speedfan as they ascertain the temp from the processor directly (whereas Speedfan gets it from the socket edge). The actual temp is usually 5 - 10 C warmer than Speedfan. You could be really as high as 30C - which is still very cool. My system is idling at 40C.

2. One reason why you are so cool, yet unstable at over 2.5 Ghz could be your Vcore which is quite low at 1.2v. Try it at 1.4v to 1.45v, or auto, and you should go stable.
 
stock vcore was 1.35v on a64 chips iirc, so set it to that to start with, no point undervolting it if you want to find the max clock...
 
I would also find out what the default voltage for your RAM is and set it to that figure instead of it being on auto, I have the same board as you pretty much and I think I had problems when it was set to auto. Also, just incase it's causing the instability, you should reduce the HT link speed to 800MHz until you hit 250 FSB/HTT as you don't want/need it to be higher that 1,000MHz overall.
 
sorry guys i keep getting my information wrong. The processor voltage is (as v l per) says 3.50v
The +1.20v is the pci-express voltage (which i presume is the graphics card voltage.

DDR volt is set to auto. Anyone know what the standard voltage is for my RAM (in sig). Also does anyone know the answer to my RAM divider problem (my last post)


Thanks guys help is much apreciated
 
I already had core temp sorry i didn't mention it. I just checked it and it jumps between 23C-25C i'm not sure wether the changing temps is right?


It also says the max temp should be 55C. Is that right?
Also what does TDP mean? it says it just under 'max temp' and TDP reads 38.2watts so is obviously something to do with power, but what excatly?

hit problem's....... again

well first of all i can't go over 260mhz (on x11 multi), i have upped the processor voltage to 4.00v but still the computer won't even get into the desktop without restarting

Next is the jumping processor voltage and the high voltage. I have it currently set at 3.75v but speedfan reads 1.408v. Is this just a wrong reading or is there something wrong?

I really hope it's not! That's far too high to be right. It should be somewhere around 1.4-1.5v. The reading SpeedFan is giving you (~1.4v) is correct ;)

Stock voltage depends on revision:
E4: 1.4v
E6: 1.35v

CoreTemp will tell you the revision, and for the moment set it manually to stock voltage in the BIOS and leave it there :)

Whatever the 3.5-4.0v setting is, set it back to what it was originally, because it's definitely not the processor!

sorry stupid me again, having a bad day lol
it was 1.350v. I have now had to set it to 1.375v to keep it stable, but even if i set it to 4.00v it still won't go above 260 (processor freq), why is this?
Also had to set the HT link speed down to 800mhz as the system didn't like the 1ghz and just refused to even go to desktop without restarting itself
 
If your multiplier is still on 11x, then 260mhz FSB gives you a CPU Clock of 2860Mhz (2.86Ghz). That's pretty high (especially if it's an E6 core) and it might not be going any higher simply because that's the chip's maximum frequency at that voltage.

Having the HTT Link down at 800mhz will make very little difference, so little that it's probably not even noticeable.

Try pushing Vcore up to 1.4v and then see if the chip will clock any higher.

I have a feeling though that you're almost at your CPU's limit :)

Jon
 
Well you have got it up to nearly 2.9 Ghz on air which isn't bad. You should really get the voltage to the 1.4-1.5 range to improve, after which I guess you're into tweaking ram timings (assuming decent memory), and or improving cooling...

I'll now move over for the hardcore types... :)
 
got it to 2.860ghz according to CPU-Z. Pity i can't push it further really because i have fairly low temps. coretemp says i have an idling temp of 32C

So i'm looking at overclocking my RAM now. Any adivce? Thanks
 
1) What voltage are you running it at the moment?
2) What's the load temp?
3) Is it stable at 2.86Ghz?

Idle temps don't really matter, you need to stress it and find the load temp, that's what counts.

If the load temp and voltage isn't too high, you could try pushing a bit further with a bit more voltage.

RAM timings can help squeeze a bit more performance, but the main thing that will gain you real-world speed with an AMD64 CPU is raw clock speed.

1) 1.375v
2)i have stressed it using S&M and the max temp it went to was 45C
3)Yes

If i push it any futher it will just refuse to start. I have tried upping the voltage to 4.00v (the max voltage i can go to) but it still won't over 260

Again, 4.00v is far too high to be a plausible Vcore voltage. Most, if not all, motherboards will simply not allow you to put that much voltage through the CPU.

Do you mean 1.4v? ;)
