W700 and W701 Overclocking?

[james60007]

I have a W700, QX9300, passmark CPU rating 4180;
a W701, i7-920XM, Passmark CPU rating 3380;

Both Window Experience Index are 7.2

Loaded ELEET on both, it seems temp on QX9300 has been low around 43 C all time;
i7-920XM has been in the OK range 50-70 C.

Is there anyway to overclock both machines?
Thanks in advance.

According to this voluminous, detailed thread, W700 Extreme models can be clocked, but non-extreme and W701 cannot.

W700 is referenced several times, so it appears someone has done it successfully.

Thanks a lot!
Now my W700 works beatifully at 3.5 GHz.
The PassMark rating of the CPU is at 5510.

Still looking for a way for my W701 i7-920xm tho.

Merry Christmas!

I haven't installed the overclocking code yet; did you find it easy to install and use?

[james60007]

Yes, installation was easy and I just finished Prime95 and settled at 12X, 3.2GHz

Have you tried the program SetFSB on the 701? Not sure but that might work.

[james60007]

I tried several things, ELEET, THROTTLESTOP (thanks to friend on this board), CLOCKGEN, etc.
I downloaded SeTFSB, I might get it wrong. it didn't work for me.

Right now the only thing works is the THROTTLESTOP.

THROTTLESTOP shows QX9300 (W700) different than W701 (I7-920XM), with QX9300 having much easier setup.
The link above didn't say it would work with i7-920XM, however, I could right click and change TDP to 65W (from 55w), current to 52 (from 47?), then I could change multiplier of core/thread 1/2 to 28
core 3/4 to 27, core 5/6 to 23, core 7/8 to 23.

This is the only way I found working with W701 (i7-920XM), and the passmark CPU rank got a 550 boost.
I am not sure it is a right way tho. It has been stable so far.

Please keep us posted on overclocking your W701. I'm due for a Tpad refresh in a few months, and I'd almost decided upon going w/W700 overclocked vs. a W701 with the 920 chip. If there's a way to speed up a W701, then I'd just go with that or whatever W70x replacement Lenovo announces in the next month or two...

Didn't think there was a way to speed up a W701.

[james60007]

I tried THROTTLESTOP 2.90 beta 6

Was able to move CPU passmark another 600 points higher.
So using OCing, I could add 1150 point to i7-920XM.
This was done by moving TDP much higher to 78, TDC to 68,
24,24,22,22 multipliers.
With TDP and TDC moving much higher, the CPUs could run at higher temp, up to 99 C.
I don't like this too much.

On QX9300, I added more than 1700 points (at 5500 now), temp is under 92 C.

So, am I reading all of this correctly?

* Unclocked, the W700/QX9300 chip has a performance rating ~33% -HIGHER- than the W701/920XM chip?

* Clocked, you get ~25% improvement on the W700 and ~10+%(and a lot of heat) on the W701?

If this is correct, and you don't need a specific feature of the W700(more memory, gpu, etc), then the W700 seems to be the clear winner, AND a LOT cheaper...

[james60007]

I think it is case by case situation.
The latest i7-920XM I have, when over-clocked at 25X
I got a passmark score of 6000.
and the temperature is around 81C for Prime95 test.
This is the one with Dell M6500, but M6500 runs very hot on the bottom. You can't put on your lap without a cooler.

The W700 and W701, on the other hand, have heat venting to the side/backside and is much cooler, even tho the CPU temp is quite high.

I guess when you run over-clock, a quiet W700, W701 might not be a good thing, the fan speed would not go much higher and noiser when you need it. Maybe somebody can help with a software which will make the fan work harder.

The average passmark for QX9300 is 3781, I got over 5500 when @13X 266MHz, about 3.45 GHz. But as a whole system, the W700 has 2 less RAM slots and the FX3700M is inferior to the FX2800M.
