Wtf.. Installed the zalman 700 on my 7800gt and it artifacts..

[MiranoPoncho]

After installing my new bios chip and the 700vccu on my 7800gt, It now has artifacts, all over the screen, ranging from green to misc. ASCII characters adorning the screen. I followed the instructions to a t but it seems I did something wrong. help would be greatly apprceated.

Are you sure it's making proper contact with the core? Put the old heatsink back on and see if the artifacts go away. If they don't, take off the HSF and check to make sure you didn't crush/chip the core in any way.

Probably has to do with the new bios, not the cooler.

"Installing new bios chip"???? You mean you actually soldered on a new chip, or you flashed the bios with a new version? If you flashed, just flash back to stock.

If you soldered, you've got bigger problems.

I just assumed he installed a new BIOS chip into his motherboard. If that's not the case, then yeah, he's got problems.

 

[NoStateofMind]

Why would anyone change the BIOS chip? GTX 512 speeds?

Remember people, when overclocking, adding new hardware, making any mods, flashing bios, installing new chips...

ONE STEP AT A TIME!

If you combine things like changing your bios and a cooler at the same time and get errors, you won't know which change brought on the errors.

Take your time and you'll be much happier with the result.

whoa...my screen just flickered...the OC gods might think I was too mean with the way I said that...sorry.

Avalon is teh winner. No soldering required, I got a replacement chip via evga, poped the old one out put the new one in and the mobo posted fine, abiet with horizontial artifacts and such. anywho, anyone know what channel on an evga sli motherboard at which the fsb frequencey is locked/ independent of?

Should be a PCI-E lock in the BIOS...I'm bored, so I'll check for you.

In the meantime, might want to pop in your old bios chip and test from there.

100.

No way with the old bios chip, 'twas defective. Just looking for one channel of sata which was locked in terms of fsb and such, unless they've changed motherboard archetechture within the latest generation of nforce.

 

[zagood]

Ah. Hmmmmm, don't know about that one specific thang, but PCI-E lock should be set to 100.

"SATA drives like to run at 100mhz ie 3x33mhz pci bus speed"

[MiranoPoncho]

Danke, but I wa trying to find out what sata chanel to put the drive on to prevent curruption due to overclocking of the cpu and ram.

Usually on the nForce4 controller instead of the Silicon Image Controller... Should be ports 3 or 4... Does the nForce4 SLI have a SIC actually...? Not sure about it...
