Here's what I can do in BIOS.

CPU Host Clock Control [disabled]
xCP Host Frequency (Mhz) 200
xAGP/PCI/SRC Fixed 66/33/100
Memory Frequency [Auto] *(this can be changed to 1.33,1.66,2.00 or auto)*
Memory Frequency (Mhz) 333
AGP/PCI/SRC Frequency (Mhz) 66/33/100

Thanks

PS. Its a 8IG1000MK. When I do a search for this it comes up as a GIGABYTE it also says GIGABYTE on the board, but CPU-Z say Seanix.

I don't believe that statement is correct (going on what i've found online so far) - it helps to optimise textures but doesn't 'clip'.

Do you have a link to anything on AI that says it does clipping?

That's your mutiplier - can't change it.
That's your FSB (front side bus).
Those are the busses to the listed interfaces. You want to lock them at the listed speeds.
Those are your memory dividers. Available dividers change based on your current FSB setting.

Hammer, get a hold of some decent PC3200 memory, so you can run the FSB and memory synchronously, and you'll see a boost in performance. P4s thrive on bandwidth.

That's your mutiplier - can't change it.


I can enable it and than I have to option of entering a number 100min to 355max for the xCP. I forgot to post that part. So I assume I can change that to 250?

Sorry for all the ?. I read some of the stuff a OC forum, but its alot to wade through.

Cheers


EDIT. Changed it to 250, I now have a 3G Processor Leaving The Memeory Freq at AUTO put at 3:2. I'm good to go!!

I may do that, I plan on a upgrade in the future, and i'll give this one to the kids. But if this works well, I might just change the RAM out. OC my 9800 Pro and keep it for myself

Oh, sorry, apparently that's your FSB. As you may have figured out, every BIOS is unique in its terminology, so it can be confusing to deal with the terms used in an unfamiliar BIOS.

Yeah, the volume of stuff at overclockers.com can be overwhelming. Get Prime95 to test your stability, and if it that runs stable for a while, you're good to go.

P4s do thrive on bandwidth, but the amount that that effects actual framerates is exaggerated. You would get higher frames with DDR400, but I'm sure they'll be just fine with your current memory.

Migkiller,

Sounds like you are 'smokin' an' jokin" I trust you downloaded the PCI Latency tool? Enjoy you tuned up rig. Amazing what these boxes can do these days.

Thanks for your help Joe!!

Hi guys I have been watching this thread as I have just put in the same card a Migkiller ATI 800XT, im not getting as good a FPS in Lomac as I thought I would, IL2FB trippled in FPS on the same settings as my old 9700Pro, Lomac went down.

Anyway I have done a clean isnatll of Lomac and would like some with simlar setting to me to post there in game Loamc settings and FPS in the default Flamming Cliffs A10 instant start mission.

My specs

MSI K7N2 Delta ILSR
AMD 3200XP
ATI 800XT 256 (Cat 5.6) 2xAA 2xFSAA AI set to ON
2x512 meg DDR

I have done the PCI Latancy timer and set it too 64, defrag is done and all the normal stuff gamers do to WindowsXP to tweak it.

Memory
DRAM Type DDR-SDRAM
DRAM Size 1024 MBytes
DRAM Frequency 200.4 MHz
FSB:DRAM 5:4
CAS# Latency 2.5 clocks
RAS# to CAS# 4 clocks
RAS# Precharge 4 clocks
Cycle Time (TRAS) 10 clocks
# of memory modules 2
Module 0 OCZ DDR-SDRAM PC3200 - 512 MBytes
Module 1 OCZ DDR-SDRAM PC3200 - 512 MBytes


I bought some faster mem, this is the current setting. Should it be changed? If i'm not mistaken the ram is 400Mhz. And on the sticks it says Premier Series 2.5 3-3-7

Thanks

H,

You can jack up your PCI latency time even up to 256 if you want. I think mine is at 128 for the X700. It's a 256M card too. I rmember you want it to be about half the memory size of you card or other device. It helped for onboard sound too.

The "half the size of you card's memory" is usually referrenced as a rule for AGP aperture size, not PCI latency.

Memory latency should be set as low as possible in all categories on P4 systems. The minimum latencies are a function of both the memory itself and the memory controller built into the motherboard chipset. I would use a program called memtest86 to check your memory stability as you lower the latencies. Memtest86 is also a good tool for checking memory stability as you push your memory past its rated speed while overclocking.

Squiffy: FUBAR sent me the latency tool. Would you comment on my settings please?

Migkiller, adjust the latency value of number 03 (The SiS 5513 IDE Controller) down to 32. That may be the cause of your gun-stutter.

Thanks FUBAR. Like so?

Perfect!

Now, did you try an A-10 mission to see if the GAU-8 gun stutter is gone?

I used the stock mission (fly now) on the opening page of LOMAC and unfortunately, I still have the stutter. I have the sound card acceleration turned down to basic. Is there anything else I should be doing? I'm getting 30 FPS on that stock mission otherwise so that's pretty nice!

Hey sorry guys,

I left work and didn't check SimHQ again at home. Joe, thanks for the clarification on latency. Migkiller, I may have stumbled on to similar setting just by concentrating on the vcard. I still have one question for Joe and Fubar, I thought latency was the rate or bandwidth that would be reserved for a device across the pci circuits. So a higher setting for vcards would reserve more space for them. Why would a lower setting help for soundcards or usb devices?

Migkiller, I defer to Fubar who has expertise on this topic. How about settings as low as 16 or 8 for some devices? What does IDE stand for exactly?
