damn the pentium M is quick!!

Cyber-Mav · 11 Feb 2006 at 17:00

hi all, i got a laptop just a few days ago and now that its been up and running iv had time to bench mark it and its darn quick :eek:

the spec in my sig scores a super pi 1mb score of 43.summink seconds.
the pentium-M 730 (1.6ghz) lappy with 256mb ddr2 533mhz ram scores 47.656s.

thats darn quick considering the clock speed disadvantage it has over my xp-m setup.

also will bench again in a few hours, my 2gig ram kit for the lappy has arrived so this lappy will have sam ram as my desktop pc so it will be a better test.
also will see if the dual channel setup on the lappy gives any performance advantage.

should be looking at ~44 with dual channel ram. They outperform athlon 64's clock for clock so it should perform like a 3000+ (which it is)

Cyber-Mav · 11 Feb 2006 at 17:11

ahh, but will the laptop see a benefit from the dual channel ram? since the fsb is 533mhz and the current ram is 533mhz so im assuming a 1:1 ratio. cpu z says that the cpu is running on a 133fsb that is quad pumped to 533mhz.

to benefit from dual channel ram setup doesn;t the fsb have to be higher? otherwise it will be like the old AXP cpus on nforce 2 boards.?

i got ~43s with the 740 at stock speeds (133x13=1729mhz) in my desktop with dual channel geil value.

30 seconds with a 770 @ 2500Mhz. No sweat....

Cyber-Mav · 11 Feb 2006 at 19:47

damn thats quick. ok if got my 2 gig of ram in place in the laptop will run super pi now.

Cyber-Mav · 11 Feb 2006 at 19:55

ok with 2 gigs of ocz ddr2 533 4-4-4-12 ram in the lappy the super pi 1m score is 46.531 not bad at all for a 1.6ghz cpu.

although running in dual channel seems to have made only a very slight difference. guess the fsb is the limiting factor now.

wonder if the integrated gfx which is an intel chip on pci-e bus would benefit from the dual channel ram setup. shame i did not run any gfx card test before the ram upgrade.

25s with a 740

at 2870

edit..... i think p-m's like tight timings

can't adjust any timings in the bios since the advanced settings section in the bios is locked out to me. acer did a number on these laptops and limited what can be done in the bios.

i wouldn't worry about it. laptops are not meant for tinkering and as you've already found out, it's pretty nippy at stock.

cool, just wish there was a way i could get a tv out connection on this laptop, it doesn't have svideo connection, just have a vga out and usb sockets.

monkeypants · 11 Feb 2006 at 20:28

Am getting one next week! Can't wait! No doubt it'll beat my 4Ghz 630 in a Pi race.

m3csl2004 · 11 Feb 2006 at 22:10

yeah - lawrywilde on these forums have a clocked dothan rig - i have a few screenies where hes gettin sub 25 second 1mb on air

dothans really are fast

Mattus · 11 Feb 2006 at 22:22

Last time I checked XtremeSystems, the world-record SuperPi 1m was with a Dothan. Something like 19s.

Si MPS · 11 Feb 2006 at 22:24

I've got a Thinkpad T42 and i'm amazed that it boots faster into windows than my Opty 146 @ 2.5GHz

hehe. just checked and the top dothan is in second place. it's clocked to 4100mhz... :eek:

and does pi in 18.67....

just a shame the newer ones seem a little hit and miss on the overclocks, most do 2600+, i have been quite lucky the first one i got was an ok clocker, i have known people go through 3 or 4 just to find one that goes over 2700mhz.

mine goes over 2.7 but require ridiculous volts to get fully stable....

245x11=2695mhz, 1.4875v
210x13=2730mhz, 1.575v

that's quite a voltage increase for 35mhz.... :eek:

anyhoo i'm undervolting mine now to run at 2.4ghz. it's knocked 12c off my load temps still using the stock cooler :cool:

mines been at 2800 since day one.(i like round numbers.) Vcore 1.575, dont care about vcore, if it dies i will buy another

XP90c, 45c load (sys temp is 33 according to mbm5) had a xp120 on before that and that was 50c load because the base was concave i think and had a poor contact.
