Np5796 Cpu&gpu Oc

Some hardware related to voltages, power usage, and timings, prevented the NP5793 from taking a CPU and GPU OC at the same time. I'm curious if any NP 5796 users have tried to do the same on their systems, and if so, what results did you have?

I'm also thinking SetFSB might not work with the new system, at least not yet.

 

A gaming notebook that can't take a CPU and GPU overclock at the same time, are you serious?

 

Ya kinda sad... The P9300 2.495ghz would clock up to 2.95 stable at good temps, and the 8800 would clock up from 500/1250/800 to 620/1550/980 and stable with manageable temps, but you could hardly do both together. I think the best I got was 2.58ghz at 530/1325/850. And at that, it was slightly unstable.

 

over GPU OC'ed, I can OC my CPU by 100mhz max.

 

This was a known problem with the NP5793 also...It's weird they haven't fixed it in the NP5796, but I guess Clevo don't expect us to be OC'ing our GPUs at all.

 

With GPU overclocked, you can only max the overclock of your CPU by 100MHz?

 

What you guys dont understand is those without the extreme cores are only able to OC their CPUs using SET FSB which OCS the PCIE slot which causes teh GPU and CPU and the ram slot to be overclocked together, thus when you try OCing the GPU you end up Ocing it far more than you anticipated. Thats why it is hard to oc the GPU and CPU together until a method comes out in which you can OC the CPU using seperate PCIE slots for teh GPU and CPU.

EMIKE right now it is hard to OC anything on teh 5796 because Set FSB does not support the Montevina platforms, and NIBITOR does not support the9800GT, I've sent Mavke the developer of NIBITOR an email and he replied that he needs more than 2 people to send him the bios for the 9800GT for him to be able to code it. I've tried setting the device ID to the 8800M GTX since i've heard that it was the same thing but it still would not find or let me set any clocks and voltages.

Ive been dying for a new release to come out that supports the 9800GT so that i can mess aroudn with the voltages so that I can increase battery life I've only been able to get RM Clocl to work slightly. It does not read the clocks right , reads it as 2.88 sometimes, and then when i mess around with the voltages i get BSODs after about 6 hours of gaming which i guess is due to RM Clock not setting the voltages properly. So i just set the lower voltage things when im on battery since i dont do any gaming or anything intensive.

 

Whew...

That makes sense, and it never fails when overclocking using software.

 

Software OC'ing would be the same thing because you still would be OC'ing an already OC'ed GPU due to the increased PCIE slot from using SET FSB. Wish we could buy the Killernotebooks method for our 570TUs Mark's program allows the user to OC both because his program only OC's the PCIe slot of the CPU. or convince intel to unlock the non extreme CPUs, but they would never do that because no one buy the extreme cores or higher cores for that matter.

 

You know, I never thought of benching GPU speeds when OCing the CPU using SetFSB. It just didn't come to my mind that overclocking the CPU was overclocking the GPU also...

So from what you are saying, when bumping up the FSB, it is literally OCing the GPU as well? This would make complete sense of everything if that is truly what it does.

Could anybody with the 5793 (or 5796 if they can get SetFSB to work) bump up the CPU and get me shader scores from 3DMark 06 before and after CPU OC?

 

I was agreeing with you my man, LOL!

Software overclocking can be tricky, especially since it does overclock other system components. The “It never fails when using software”, was meant to be exactly what you’ve stated.

 

Stated in another thread, using SetFSB overclocks the CPU and GPU together?

 

^^ Yes, SET FSB increases the PCIe for the whole board which includes the GPU CPU RAM.

 

In your opinion, is that risky to do?

 

Is what risky to do? Cpu Oc using set fsb is not risky at all. The worst thing that could happen is a BSOD, all you need to do then is downclock the cpu a bit. As long as you dont oc from 2.5ghz to like 3.5 your fine. GPU oc on the other hand is a tad bit risky as it involves bios, but as long as you modify the bios that came with your video card and make a back up copy of your default bios and are plugged it shouldn't be bad at all. The only obstacle is getting yourself the guts to do it

 

Yeah I have had my CPU OC'd with SETfsb since about February and I haven't had any issues at all, rather stable really. My OC is from 2.0ghz -> 2.3ghz, at anything above 2.4 i get BSOD's frequently but not in 3dmark.

 

Man, I had a blast with my desktop q6600 oc'ing fsb to 3.0ghz. But I'm willing to go slow with the 5796. I do know however that fsb oc'ing DOES yield results!
Especially in crysis, age of conan, but not so much in normal use (web, office, powerpoint) so far as I could tell, it was all too fast already to notice a difference.
I wonder what other rediculessness I could potentially get from montevina platform. I would really like to work with that robson to optimize my alt tab use. Lets see what we can do.

 

CPU oc is pretty useless for gaming. The GPU will be more of a bottleneck and yield much better results in real life game performance.

 

SetFSB OC both CPU and GPU. here is my new result.

 

What is this compared to?

 

40xx?? Can't remember exactly.

 

So, recapping: it is very well possible to overclock the CPU with SetFSB, but it will also affect the GPU, so you have to pay special attention to the temperatures of both components when testing?
That's it, right?

 

It will affect your GPU on the account of the PCI/PCIE being raised. Not only will you need to keep an eye out for the CPU/RAM/GPU, but also the temps in general since it will raise the frequencies of other components as well.
With an extreme overclock of my system 2.5 to 3.1, the temps for everything only went up 3 to 5 Celsius, even with gaming. At a stable overclock of both the CPU/RAM at 2.7 and the GPU at 600/1500/950 my GPU got up to 72C while running Crysis benchmark, which is the most it ever got while running that benchmark. Overclocking the CPU pass the 2.773 would not run the benchmark at all.

With just a mild FSB overclock 2.5 to 2.8 (that is mild for me ), the temps stay the same for everything as it is with default. In other words, no temperatures increase.

 

Sorry for not adding this in the above post. But if you look at the thread here, you will see my temps of the cpu, gpu and hard drive with fsb overclocking my cpu from 2.5 to 3GHz. Notice the max temps, that was the highest it got while running wprime both test.

Notice the bottom slider of the two, that is the one you want to keep from moving. If anything, move it backwards till you see it at 33.3.
