700mhz wall on HD4850 is smashed.

[Shocker003]

Please can someone post a pix of his HD 4870 or 4850 underwater and which blocks will fit them. I have a mcw60 already or do i need to buy another waterblock for this card.

[tvdang7]

gpu-z sensors dont work right for me after my guru flash. gpu load stats at 0 and the clocks stay at 1 number unless i reopen it.
fan speed also is stuck at around 40-50% but i know by listening to it that the fan is pretty much full blast.

EDIT NM it jsut started working lol i have no idea why. owell.

Which one ? Guru's modded MSI BIOS ?

my own visiontek modded bios.

One thing to consider is what people consider stable. I'm able to push my VisionTek cards pretty high on stock voltage but it's only until I leave FurMark running that they will blow up. Games, 3DMark, etc. are all fine. Want to check stability? Fire up FurMark, set it to 1920x1200 full screen, and let it run awhile.

i stopped using furmark after having it blow my volt modded 8800gt out on me, and it was only at like 1.4 volts. happened to a few other people as well so i just stay away from it. if it runs everything i need it to, and rthdribl runs without artifiacts, then i really don't care what it does under furmark.

this is just some stuff from the 8800gt volt mod thread with some people have the fur bench kill their cards

the mcw60 will fit fine. I'm using a Maze4

I'm using this block on my HD4850. Fits perfectly

[vinteg]

other weird thin is going on though. my secondary screen is flashing like crazy when in 3D modus.

[Shocker003]

Thats good news, thanks gurusan and DemonEyez for the info, am still scared about the stories flying around about dead cards but i will be getting a Gainward HD 4870 by next week. What type of ram heatsinks are you guy using or how are you cooling the mem chips?

[vinteg]

gurusan is there anyway way you could make a bios for me wich has the clocks of a normal 4850 (including powerplay off course) and the fan settings of your modded bios?

problems i have with your bios:

flashing secundary screen
artifacts all over da place
cant disable overdrive (but thats prolly not because of your bios....)

if you could do this i'll send you a belgian beer ^^

wel seems to me like i have a bad card. even with the stock non-powerplay enabled bios i get artifacts in furmark from time to time. card does 90° with stock bios.

I'm using swiftech ram sinks on the chips and the vregs. Also got a 80mm pointed at them:



I'm experiencing a problem. Sometimes my screen will just go black and the system hangs, sometimes it gives me a BSOD of some atidag file.
It's totally random, most of the time during browsing in internet explorer.
this happens with 1.32v on the core doing 820MHz which is totally stable (passes 3dmark, crysis and atitool 10 minutes). any ideas? I get the idea it happens when the card is switching from low 2d to high 3D and the other way round.

[vinteg]

wel seemingly i have a real bad sample to oc. anything higher then 1013MHz on the memory gives me arti's in furmark.
is this realy only because of the voltage it gets? or just bad ram?

don't know, what cooling are you using. the stock cooler really gets the ram warm. mine seems better since going to water. i'm finding not much performance over 1100. also you might note that the clocks on the ram scale by 25mhz jumps so try to keep to groups of 25 like 1100, 1125,1150 etc.

Thanks DemonEyez, i have to order new ram cooler. Can´t you lock your card so that it will be in 3d mode, it may stop the crashing or BSOD
Sorry am high on for now we are losing to Spain 1:0 Germany

I just edited my bios so that the lowest state isn't 160/500 anymore but raised them to 500/750, just like the medium state. So far i'm not experiencing any lock-ups.

wehehe, I stopped watching the EK after Holland had its ass kicked by Russians.
Damn those Russians , now I had to remove all of my orange decorations

yeah i recon it does get the ram chips hot. like you said, i am still on stock cooling. i personaly think it is kinda weird that small heatsinks keep te ram chips cooler than the stock one. does any of you know this:

is the accelero in combination with the ram heatsinks it delivers enough for th e ram to keep cool?

and

does the accelero deliver enough heatsinks to cover all the vital parts on the card?

[Shocker003]

Damn we lost to spain Shiii....TTTTT!!!!!!!!! All the same thanks for the info. Am full with vodka damn i need to hit´my bed.

The problem w/ the stock cooler is that the heat from the GPU heats up the RAM. Any aftermarket cooling solution that doesn't cover the ram will keep the RAM cooler.

[cuhaos]

What do you guys have to cool your VRM area? mine is scorching hot under load.

I've tried stock cooling and I've tried some of those thermalright ram/pwm sinks on them and they get too hot to touch under load. Im using the 720/1100 msi (with added 0.05v) bios.

[gurusan]

i am using some spare ramsinks and have a 92mm fan blowing across the card.

[biftek.]

I'm using the heatsinks that came with my S1.
I do have 2 sets of low profile Enzotech sinks coming in though.
My card is kinda ghetto'd atm. =P

[biftek.]

Just flashed my visiontek with the msi bios that was provided a few pages back. Everything works great except the 2d clocks. its staying at full blast.

Mine did the same thing.

Only mine did it because I have two monitors, and that forced it into 3D mode all the time.
Dunno if that applies to you or not though

[GAR]

How come overdrive gets disabled once you overclock within in the bios????

[barong]

anyone have the bios for maximum core without pencil mods?
alsa can i hit 800 without pencil mods?
and can i change vcore with RBE without pencil mods?
please help i would like to hit 800

[tvdang7]

lol i have 2 monitors too but i figured it out.

i unlock the states .

and use 7 , 8, 9 along with the other states that are already used.

7 for 2d 8 isnt important and 9 for 3d .

this fixed it for me. when you save the bios and reopen to look at it it will be greyed out and the clocks are not the same as what you saved it as but it works and reads fine

might sound confusing but if anyone needs picture help i can provide.

AHA!
Thanks!
never really thought about playing around with the states, I only came across it because I'm selling one monitor.
Will be nice when I go back to duals
