pierrick30 said:i was wondering about a max temp for the second sensor of the x800.Im watercooled so the core doesnt get higher than 43°C even with 1.7V Vcore but the other sensor can go up to 65 especially when OCing the RAM.The PCB is really hot to the touch.What would be a "safe" value?
pierrick30 said:65 is really the highest limit when OCing
i usually have 40°C in idle and about 50°C in fulli didnt mod the VDD and VDDQ .
my Vcore is currently 1.65V
MeridiusZN said:I have the following problem: ...my X800SE goes well OC...with no vmod to 580/560. With Vgpu mod 1,53 i can hit 620 MHz on GPU...but when i had tried Vmem mod..something strange happend. I had changed Vmem from 2,02 to 2,05....OC on mem rose up to 575...but with Vmem 2,1 it went to hell...i couldnt set clock of memory modules higher than 550 and massive artifacts was showed everywhere. Even when i had changed VDDQ to 2,15....what is the problem? I have zalman V700Cu on GPU and small blue zalman passive coollers on memory modules. THX.
EDIT: all vmods i have mentioned was pencil mods according to instructions on the first page.
malik said:Hi guys i did the mod i have the vcore at 1.69 620 on core watercooled but i cant get more then 590 out of the mem i have vdd at 2.08 and vddq at 2.16 whats the max i can go on the vdd and vddq?I didnt do the overcurrent voltmod will i be ok and can i run the vdd and vddq at those settings 24 7? Whats the max i can put on agp voltage in the bios its currently 1.6 and does raising it help ocing?

"VR IGPU Over Current Protection Vmod
Locate resistor R1596 in Image 5 and set your VR to 250k. Check the resistance on the resistor to compare after you solder the VR on. Again after soldering the VR on check the resistance. Like with the pencil mod you want to drop the resistence around 20 Ohms."
Should be 20kohm not 20 ohm.
B)
Pencil Time
For example if your starting Ohm reading is .418k and your new reading is .400k obviously it's a 18k drop in resistance."
Its not really wrong but unclear and invites to confusion. Better write 419 ohms and 400 ohms.
Urlyin said:Those settings are fine for 24/7, to go much any higher you should have active or passive cooling in place ... raising the AGP voltage in the BIOS will not help your VGA card over clock, it can help with stabilizing the NB for higher memory settings on Intel chipsets ...
Unregistered said:Thx man i have a his x800pro vivo @flashed to x800xtpe gpu i have the saphire bios right now whats the best overclocking bios for x800xtpe in the bios collection i saw a x850xtpe bios for agp is it possible to flash to that bios?
Urlyin said:Can't say that I've tried it but with different cores I would say no .. I've always used the ATI BIOS, some work better for others....
Unregistered said:Thx for your help whats the bios that oces the highest? I heard changing to the xt bios instead of xtpe might help goin higher?
Urlyin said:NP ... that could be possible... depends on the cards in most cases, if your card has memory that ocs well then a BIOS with more aggressive memory timings will work good for said card, obviously if the card doesn't have memory that ocs well then you'll need to chose a different BIOS. I've found it's best to test a few and find which works best for your card. You can also use a BIOS editor like Rabit to view BIOS settings and or ATITool to make changes to the memory timings
pierrick30 said:woukd like one too XD
but due to the very large number of memories available on all cards(u can even have different revison with different ram) i doubt he can provide us optimal parameters for each one of them....
Cally said:I would love to do this mod but after all the trouble I had just doing the flashing for the first time I don't dare think about this. My hands aren't steady enough anymore to do this work. I can't see sending my card all the way to Viperjohn just to do the volt mod. If there was someone in central Va. that did the vmod I would ask them to do it. Other than that I will just run the card as it is.
The knowledge on these forums is terrific though. People are lucky to have so many smart people together on one site.
