I would be grateful If anyone running an Ultra-D wouldn't mind having a deko at the bios chip and either posting or mail me the chip codes please :)

What you want them for ?
 
What is BIOS saviour and where can I get it from? Do I even need it as I BIOS flash from my HDU. I found 39MB unallocated space yesterday in Disk Management so I formatted it in FAT and have shoved all my BIOSes on there. Now all I use is a boot disk to get me into DOS and it's all there ready, about 10 different BIOSes lol.
 
Thanks yet again [timko]. I doubt i'll need it as I flash from my HDU. I only have to worry about power outages.
 
The IOSS website is here ...

and if you google, you'll find plenty of reviews of the BIOS Saviour. The IOSS site lists retailers for their products. Their tech support is very good, I bought a RD2 Pro and have been very happy with it, and the tech info they gave me in response to some queries I had. People in the know say if you're going to flash the BIOS, you should have one. Given that even overclocking can corrupt a BIOS, it could be something you're very grateful of if the excretia ever hits the ventilation system with your PC :D

Tried that. I dont have problems with cold boots. Once its booted and you go to restart again it gets all the way to 'Windows shutting down' the monitor turns off but it does not make its 'beep'?

Is anyone else having this problem?
 
DFI NF4 memory question

I'm upgrading my P4 setup soon to an A64 3700 San Diego based system, and I'm hoping to use the DFI NF4 SLI. My question is, my current setup uses 2 x 512Mb Corsair XMS3500 Platinum, which I believe use BH-5 chips, which folks seem to get good results with. My other option is to sell the XMS3500 with the rest of my system, and get some of the following: Corsair 1GB DDR XMS4400 TwinX (2x512MB) CAS2.5 (TWINX1024-4400C25PT) (MY-068-CS) - which are I think TCCD based, which seem more problematic.

Which would be the best option? I plan to OC, but not to extreme levels, maybe up to 2.5-2.6GHz if possible?

Some advice would be welcome. I love planning upgrades - exciting and free at this stage!
 
2.5Ghz and 2.6Ghz are most definitely possible with a SanDiego 3700.

As for the RAM - it's only the Corsair TCCD sticks that some people are having troubles with. Any other RAM company with TCCD (G.Skill, OCZ PC3200 Rev.2, Patriot XBLK) don't seem to have the same amount of issues.

In general, BH5/UTT type ram will get to a max of 265Mhz - 270Mhz but to get there, you'll need **at least** 3.5v and upwards = lots of heat and will **definitely** require a fan over them to stop them from overheating and dying.

TCCD based RAM on the other hand will easily get you upto 300Mhz, and over if you're are clever enough with the many memory settings (*not* just the basic 4 settings) but will only need at most 2.9v - 3.0v.
 
BIOS 414-1 for TCCD, 201x11 is fine, but when I try and do 220x10 or 210x11 with a 1:1 or 166 divider it locks in windows or at the IRQ settings, tried max voltages and it still does it :mad:

Try BIOS 414-3. Apparently this is a lot more stable than 414-1. That's what I'm running and I'm priming at 2.75ghz, so far 2.5 hours stable. (I have TCCD too).
 
I've been chugging away just fine with 414-1 and my OCZ Rev.2 TCCD (currently at 305Mhz 1:1)

Concorde, is the ram you are using the same ram that you previously achieved 300Mhz with? If so, I note from your post they you are trying to jump from 201x11 to 220x10. Did you remember to relax *some* of the memory timings a tiny bit?
 
How many volts [timko] for 305. I'm trying to get mine up there. I will point a fan on the ram (80mm) as well as the PWM IC. Also, did you adjust settings other than the main 4?
