Motherboard Won't Support Newer Video Cards

[Thermopylae_480]

I just bought a Sapphire HD 3850 and it does not seem to work in my motherboard. Neither will my brother's 8800GTS. Both cards seem to work fine in another system though. My old XFX 6800 GS worked fine though before I sold it yesterday.

Neither card will display anything.

try updating the bios ? seems strange it shouldnt work with newer cards if you ask me maybe a bios issue

[Thermopylae_480]

Last BIOS update is from Jan-2006.

[pt]

isn't that mobo pci-e slot 8x?
i think that's the problem

i think that's the problem

well spotted i heard a while bk that the 8800*s needed 16x but surely it would still work with 8x just might not get the full bandwidth the card needs

latest bios jan 06 damn thats nearly 2 years ago, no newer releases

@ PT can't be because I've seen P35 boards run the second HD3850 with 4-lane width in Crossfire.

@ Thermo, use your old 6800 to override the PEG negotiated bandwidth using the BIOS setup. Decrease it to 2 lanes slot in your HD3850, then go 4...8...16 Use the IF..Then..else logic....you get me?

[Thermopylae_480]

Can't shipped my old card to ebay buyer before the 3850 was delivered. The only cards left are 3850s and 8800s. I might be able to get a hold of an X800 tomorrow.

What do you mean by "IF."

[Thermopylae_480]

PCI-E slot 1 is 16x anyway.

IF...Then...else (simple BASIC syntax, our jargon)

Plug-in Old card....override negotiated lanes to 2.....plugin new card....If it works, then carry on or experiment with a higher lane-width, else (if it doesn't), go back to the old card, override the lanes to 4.....continue this loop until you succeed. Alternatively, keep a check on the PCIe Clock-gen and voltage.

Sure, but it's in the older Intel chipsets' errata that it mis-negotiates PEG lanes on POST in rare cases which is why the option to override it is with the BIOS.

Humour me- take out one stick of RAM, swap them around, use other RAM etc etc

[Silverel]

Like a mathematical statement. If->then->else. Think coding.

If X isn't the answer, Then y is the answer, Else X was never the problem.

-edit
yeah that was a little late :p

Durp. I thought "IF" was some abbreviation you through in since it was in all caps :) . I know what logic is.

Good job, you win. Shitty board doesn't like some of my memory. Now I have to decide, if it is the memory or one of the slots is bad. I hate this board. My friend gave it to me free along with the Pentium D, but the board overclocks horribly, and seems to have memory issues.

-Thanks everyone

[btarunr]

Everything looks okay with your specs, you might want to try the two things I earlier pointed out,

Which is your BIOS vendor? Have you tried resetting it (clear_cmos)? I think with some Award BIOS there is an issue with you having to "Reset Configuration Data (Clear DMI pool). I'm not sure with this. If you're not losing big deal with clear_cmos, give it a try.

[hat]

It is an ECS after all... :nutkick:

:toast: Glad to have helped. A friend used to have an ECS board and I remember that we had to swap out his memory when he got it.

[btarunr]

^ Hey good job. Goes on to show for tough situations, the solutions are often simple, often ignored.

[Thermopylae_480]

Cheap board. I played with switching my memory around for an hour, and now everything seems to be working. Very touchy board, but what can you expect from ECS?

Dude, keep off ECS with your next big purchase. I sold a lot of stuff to pool up and buy a ECS board based on the nForce4 Ultra. 2 months later a capactor leaks and I'm left in the dark. Their tech support is rudimentary.

Are you able to use both/all your modules?

that reminds me of the K7S5A-pros BOOM goes te caps but you could send them back in and get a replacement board even after the warrenty ended which i thought was one hell of a good job for ECS!

as for oc'ing im surprised yours sucks even w/o bus locks it took a celeron D 351 up to 4.2ghz on stock air using an ECS P4M800-pro mobo?

have you looked at a FSB mod on your PD yet?

wait i think we talked about you doing that already...it was a no go

[Thermopylae_480]

Yeah, I'm able to use all four now. I never would have bought ECS personally. My friend made that mistake, because he needed a cheap Pentium D board. I ended up trading my Abit AA8 Duramax and a Pentium 4 530 for this Pentium D and board. It was free, and got me dual core, so I really can't complain to much. It overclocks horribly. I really miss my AA8, it was wonderful.

Mine was a KN1 Extreme. You're luckier living in the US which has strong consumer-empowerment laws, you can sue ECS even if they sent you a torn plastic cover. I don't have that luxury. My Q6600? Well that's a B3 revision chip (different fab) it heats-up a lot compared to the newer G0 revision. It can OC just as well but hotter. I'm doing ~3.2 GHz using air-cooling living in a semi-arid country. It's almost texas everywhere (woot). Comparing the stabilities of a singlecore Cellie and a Quadcore Q6600 over 4Ghz is not wise. Cellie runs cooler than a Q6600 any day.

[cdawall]

those cellies are nice but they top out really fast they have that whole "FSB lock" thing...

[btarunr]

FSB lock? What's that? I heard of multiplier-lock but not this. The only Cellie I ever used was the Cellie 300 MHz Slot processor (w000t). Every Intel Core processor that's not an "Extreme series" has a upward multiplier lock (you can change the multiplier, but only downwards). Pentium D has no lock whatsoever. But well, Thermopylae doesn't need a room-heater (pun) :laugh: j/k

I had a problem where my computer would POST and turn on but wouldn't display an image with the 3850. It turned out something was wrong with my monitor's DVI, when I used the analog cable it worked fine so I had to replace my monitor. Do you have another display you can try it with to make absolute sure its the cards? I even RMAed my first 3850 thinking it was the card and it wasn't until the second one came and wasn't working that I realized it was my monitor.

[cdawall]

i got it form being on XS the cellie chips have an issue going over 4XXmhz fsb speed giving max oc's in the 4ghz when everone knows they could be clocked a lot higher

i have seen several of these chips on the stock POS cooler hit 4ghz so cooling is not the issue
