    Can I decrease my 4850's IDLE clock speed?

    Underclocking the RV770 core even more on your HD4850 is not going to make much of a difference at IDLE. Going lower than 500MHz might shave off 1W or so, but that's it. You might get some savings underclocking the GDDR3 memory down a bit more from the IDLE clocks, but there also isn't much...

    How do I edit the .rom file to add support for a new CPU?

    I'm guessing you already tried running the Celeron 450 on the ECS board, and it didn't work? I don't see why it wouldn't. If the motherboard supports the other three Celeron 4xx processors (420, 430, and 440), then the 450 should work just fine. All four are the same exact chips, just...

    G. SKILL FALCON SSD's "Mis-Reporting" Buffer Size ?

    Tell your friend to stop worrying. All Indilinx-based MLC SSDs (Supertalent, Gskill, OCZ, etc...) have 64MB of onboard cache. The programs used to read the buffer info are just misreporting it.

    4890 VOLTAGE and CLOCK tweak tool

    Rivatuner also can adjust (????) voltage. /wi1,71,18,3c - Default 1.20v setting. It is easier with GPUTool though. I'll give you that. :) But they don't. Newer HD4890's built with non-reference PCBs (Sapphire Vapor-X, MSI Cyclone, XFX ZDFC) lack the necessary Volterra VRM chip(s)...

    ati2evxx.exe question

    You are correct in your finding of ati2evxx.exe's function. It is not necessary for proper operation of your video card. I have the ATI Hotkey Poller service set to "Disabled" in the Services menu, with no ill effects on my HD4870 512MB + WinXP x86...

    Solved - Thermal pad for vrms on the 4870 stock plate

    By "extra cooling", I meant you don't need to put heatsinks on them. In all likelyhood, there will always be some moderate airflow over those large PCB components, either with the stock cooler, or if you used something like an Accelero Twin Turbo...

    Solved - Thermal pad for vrms on the 4870 stock plate

    The hole in the stock cooling plate is mainly for PCB height reasons. The tall VITEC inductor and PULSE vrm modules have large surface areas, and do not require any extra cooling. The stock cooling plate is a big slab of steel. Just what is needed for those pesky hot VRMs...

    Solved - Thermal pad for vrms on the 4870 stock plate

    A long while back, I used the iandh HD4870 cooling kit on my reference HD4870 512MB, along with an Accelero S1. VRM cooling was highly ineffective, with that useless, thin aluminum heatsink. It's just not enough surface area to properly dissipate the heat coming off the VRMs. Stick with...

    MSI Radeon 4870 1GB - 158.99 AR + ship @ ZZF

    MSI Radeon 4870 1GB - 158.99 AR + ship @ ZZF

    If you get the version with the reference exhausting blower fan cooler (as seen on Zipzoomfly), it'll have the original reference 3-phase digital VRM PCB design. If you get the version with the non-reference standard-bladed 80(?)mm fan cooler (as seen on Newegg), it'll have a non-reference...

    Installing Xigmatec 1283 on Gigagbye EP45-UD3P in P182 - Best direction to point fan?

    I had the same questions, a number of months ago, when I first installed my HR-01 Plus in my Antec P182 case. Test #1 Scythe S-Flex SFF21Fs (both ~1000RPM) in both the top and rear spots, exhausting air out of the case. Scythe S-Flex SFF21F (~1000RPM) pushing air through the HR-01 Plus...

    HIS 4870 1gb vs. Sapphire 4870 1gb?

    Avoid the HIS card at all costs. The cooler on it is absolute garbage, and is horribly underpowered for cooling the original reference 3-phase (very hot) design. Only the original stock dual-slot exhausting cooler is recommended for this PCB design...

    If you already have a properly working SP2 installation with all of the updates downloaded and installed from Windows Update, there is really no reason to waste your time with SP3. In the future, as others suggested, if you do a clean re-install of XP it would be good to utilize a...

    AzenX Blitztorm - anyone used this for cooling vrm, ram chips?

    I doubt it's the memory that's giving you a problem, it's the VRMs. If you're trying for passive/semi-passive you need a very generous heatsink over the VRMs, properly secured and in contact via either thermal tape or TIM. Also, from what you write you're OC'ing while running semi-passive...

    EVGA Announces GPU Voltage Tuner for GTX 260s, 280s, 295s

    Best 4870X2 I've seen

    One thing I'd like to see is what the difference is in system temperatures (CPU temps also), comparing the reference HD4870X2 cooler which exhausts the warm air out of the system, and the non-reference HD4870X2 cooler which dumps the warm air into the system. While the non-reference HD4870X2...

    Powercolor 4870 1gb pcs+ problem with 8.12

    The flickering you get when changing memory frequencies with the HD4870 occurs with all the compatible Catalyst drivers (8.6 Beta through 8.12 Final). ATI's implementation of GDDR5 memory and overaggresive PowerPlay state changing is the cause of this. Best bet is to just lock in your...

    Flashed my sapphire 4870

    BIOS flashing can fail in both Windows and DOS. It's just more prevalent in Windows. There's no reason to be scared to use either method, or to not do BIOS modifying/flashing at all, because of permanent failure. Just make sure you have a backup PCI video card. You simply boot up off...

    How to stick memory heatsinks on VGA card ?!?

    I too can vouch for the Sekisui 5760 thermal tape. Excellent stuff! Has done a great job on my HD4870. After properly cleaning both the surfaces of the memory and memory heatsink, the thermal tape bonds both together very securely. I've also used it to hold heatsinks to the VRMs and other...
