overclocked Turion

[aggiebroz]

I overclocked my Acer Ferrari 4005 very well with all stock cooling. I raised the system clock to 220 which got the ML 37 running at 2200 mhz. I had to raise the vcore from the stock 1.35 to 1.4. The ATI x700 was clocked from 358/330 to 410/380. The most amazing thing though is that i got the stock DDR333 ram to run at DDR 400 speed even with the high FSB and CL2.5. I have a screenshot after running 3DMark05 and screenshots of the ram being overclocked.

Have your temps changed with the OC? Plus is batt life the same?

 

[aggiebroz]

the temps went up a few degrees so now under high graphics and cpu load the CPU temp is at 73-78 C from a stock 70-76. I don't have a GPU temp to monitor. I am not going to run it overclocked on battery bc it is not good to over stress batteries. With with high performance settings while gaming it gets 50-60 min on a full charge with stock timings. word proccessing and email gets 3 hrs or more.

oh i should mention that it will only remain stable at 2200 mhz for about 20 min of heavy load so i can only game with it at 2140 mhz. the gpu will over heat sometimes after about 1-2 hrs unless i back it off to 400/370.

To bad they don't OC like PCs.

Did you try to lap the GPU & CPU heat sink then AS5?

If your system has a heat pipe try to polish the heatpipe. My system's come from my ODM with all sorts of imperfections on the heat pipe, and I can usually get 2 C at LEAST polishing the impurities out.

thanks for the tip, yes my notebook does have a heat pipe in it. This summer when the waranty end i might replace the cpu with a MT40 and then when have it opened up i could do some work to the heatsink and such. if i do that then i will really oc the ml37 in a desktop.

Might be interesting to hear all the programs you used to overclock your laptop.

 

[aggiebroz]

to change the system clock i used ClockGen from cpuid.com, to change multiplier and vcore i used CrystalCPUID. To monitor the CPU temp i used AMD Dashboard Demo(many other programs can do that), to show the actual core voltage i used AMD Power Monitor (Turions use a different VID table that most programs like cpu-z and crystalcpuid show incorectly) I overclocked the x700 with ATITool. The ram speed was changed using A64Tweaker. btw i found out that the ram overheats at DDR400 during games even though it passed a few stability test programs. All system changes were done in windows as a laptop BIOS has no options.

system specs: Ferrari 4005
Turion ML 37
1 gb ddr333
100 gb 7200rpm (that was a great upgrade from the standard 5400 rpm)
ATI x700 w/ 128mb - updated to catalyst drivers

You might want to try the RAM I use. Patriot Extreme Performance part #: PEP1G2700SLL 2-2-2-5 timings... designed for overclocking.

 

[aggiebroz]

thanks for the suggestion. i checked out the patriot web site and that ram is DDR333 pc2700, do you know if it works at DDR400 pc3200 speed stabily at a a latency lower than 3. If not then i will probably get ram rated at DDR400 with either CL 3 or CL 2.5.(i'm sure the slower ram would go faster if i had a way to up the voltage to the 2.6V that the faster ram uses)

 

[killernotebooks]

It's specifically designed for overclocking. You're going to get more speed from the lower latency than the bandwidth. I read an article where they O.C.'d it, of course with a little loss of latency, but gained back the bandwidth you are looking for.
My memory page has a link to a pretty good ExtrememTech article on memory.

 

[aggiebroz]

thanks for the link. it would have been nice if they would have compared ddr333 at various latencies to ddr400 at various latencies. i know when i ran my laptop with the ram at ddr400 cl2.5 i could notice the diff over ddr333 cl2.5. also it was faster going to ddr400 cl3 from stock. when going to ddr400 with either latency rightmark memory analizer showed about a 20% increase in bandwidth and a 15-30%(depended on oc, CL, and spd) decrease in latency cylces, but i have no idea how much performance increase that is in real programs. my experience shows that going from cl3 to 2.5 didn't change much, so i don't know if it is worth going from 2.5 to 2.

It sepends on what you are doing. The article said anywhere from 2 - 4% improvement average.
