omg, is it possible to disable this BIOS watchdog

uninstalled XTU and tried 12/12/12, even 15/15/15

still cant save ram setting

so is there a way that can force bios save ram oc setting or not?

trust me prema, i tried many times with or without XTU

im 100% sure that my ram can run at 1866@11/11/11/28, i checked with aida64 ram test, clock&timings are correctly running at 1866@11/11/11/28, and the bandwidth of ram raised to 27xxxM/s from 23xxxM/s@1600, i also run 400% memtest with oc clock&timings, 0 error

so i think my oc is ok. but somehow the oc setting cant be saved in bios

rly need ur help, thx

but no, i can boot correctly at the first time after oc to 1866, and can finish all test, and the clock&timings setting seems all right(11/11/11/28) via AIDA64, but the timings settings are already changed to 6/6/6/14 which can be seen in XTU

then, if i reboot, the system will shut down and reload default bios setting to 1600 cuz the timings setting is 6/6/6/14 at this time

thats why im so confused now

hi prema, found a ram issue but im not sure it's a bug of ur bios or not

when i oc my ram from 1600 to 1866@11/11/11/28, set directly in bios or using XTU, my 157sm will boot all right at the first time, but i found that the ram will be set@6/6/6/14, a crazy setting, and my pc wont start up if i dont change the ram setting to 11/11/11/28 again

so the problem is that ram setting in bios wont stay at the value i set, it will auto jump to 6/6/6/14 after reboot, i wonder if u can check this issue

many thx

hi svl7

i just get a p157sm from the vendor "hasee"

and i find its 780m's vbios version is 80.04.92.00.0A(P2053-0001), a little different from ur modded 780m vbios

so i want to keep this version and could u help me mod this bios to unlock all oc limit plz? and it will be nice if u can set the mem clock@1500 cuz dat is the highest stable mem clock i find, then i can focus on finding highest core clock with nvidiainspector without set mem clock again and again

thank you in advance

hi prema

just updated ur v1.1 bios for 157sm

but still no ram voltage control options

can u add it? not just a ddr3/ddr3l option

thank you in advance

did a small mod like this

added 2 pads to help pch give its heat to kb lol

temp b4 this mod running 3dmark firestrike

temp after doing the same thing

prema thx for ur reply

but i think pch chip is dat big shinny one one the right side of mb, not dat small black chip which i think is used for control cpu frequence

well so far no shutdown due to the high temp pch

but i dont think a repasting can solve the problem cuz there's nothing to repast lol

hi prema

i just flashed ur 157sm bios and got a little question

for ram mode, is that ddr3 for 1.5v and ddr3l for 1.35v?

ye but there is only 1 PCB between dat 70c PCH and 780m, the high temp maybe do no harm to PCH but i think the heat will go to 780m too

hello,

maybe i'm the newest owner of p157sm in this forum

4700mq and 780m are rly impressive, those little monsters lol

and their temps is rly good, about 40@idle and 70@dota2

but I found dat PCH cooling is rly poor, about 70@idle and nearly 100@any game, and its temp is so hard to drop

so is there any solution to save this poor PCH?
