Hey guys,

Hope someone can help with this. I've got a new build with the following specs...

Gigabyte F2A88XM-D3H AMD A88X Chipset (Socket FM2+) DDR3 Micro ATX
EVGA 500W 80 Plus Bronze Power Supply
TeamGroup Vulcan GOLD 8GB (2x4GB) DDR3 PC3-19200C11 2400MHz Dual Channel
AMD Kaveri 7700K APU
Adata XPG SX910 256GB 2.5" SATA 6Gb/s Solid State Hard Drive
Cooler Master Silencio 450 Midi Tower Case

Plugged via HDMI into my Sony Bravia TV

I've built a good few PC's in my time but not for a few years, so followed the manual to the letter, but once i started up, I had no POST, no beep and no video. But the Case and CPU fans all started and I was able to power on via the power switch.

So i tried the 'new build: no video guide on Tom's Hardware', and trawled the forums, and tried at least the following out of the case..

Tested just mobo, PSU, CPU, RAM
Checked the 8-pin CPU pw is also in with the 24-pin pw cables
Tested with VGA into TV
Without RAM, with CPU
Without CPU, with RAM
Removed CMOS battery for over a minute

In the end i sent the motherboard and processor back to OC which turned out the motherboard was faulty, got a replacement sent down, as as the 7850K was in stock, got a refund on the 7700K and upgraded to the 7850K.

The replacement MOBO (same make/model) and CPU have come down so I've set it up again, same spec but now with a AMD Kaveri 7850K.

but i have exactly the same result! Gutted isn't even the word, 2 ESO beta weekends on the bounce i'll miss! ah well, lol.

So what i'm asking i suppose, is there anything i could have missed? Is it possible to get 2 faulty mobo's in a row? is this PSU good enough for this CPU? Anyone else got this mono/cpu combo working? Do I need to update the BIOS before it will recognise the processor?

Lots of questions i know, but i'd be really gratefully for any help

Also, is it worth buying another brand MOBO to test with? I don't have access to other parts to test without buying them unfortunately...

Thanks for reading!

Hello and welcome to the forum :)

The only thing I can think of is the motherboard BIOS new enough to enable the use of the APU.
 
Thanks guys!

I'll have a look on gigabyte site & ask OC in the morning... the reason I choose that MOBO is it was advertised on OC as 'designed to get the most from forthcoming Kaveri AMD APUs'

Bit harsh they'll sell it with out it being updated already!
 
Just found this on GIGABYTE's site for anyone else reading with this issue..

Note: To enable AMD FM2+ APU support, please update your motherboard with latest version of specific BIOS and driver in Motherboard's Download section once available.

So how am i supposed to update this? Do i need an older FM2 CPU to boot, update the BIOS then swap back to the FM2+?

Are there any FM2+ MOBO's that will work out the box with this CPU?

Thanks again for the input :)
 
I don't think manufacturers put the BIOS rev on the motherboard any more.

It might be worth speaking to ocuk and they might have to update the BIOS for you or buy a older AM2 cpu and return under the DSR.

That's good to know. Would it still be worth doing a bios update or not worth it?

Well....err,

• Dont fix what aint broke
• New BIOS may improve features and performance
• Personally I do it anyway, but im lucky and have nothing to lose.
• You will need a compatible BIOS should you decide to get a Kaveri later on.
• Updating using QFlash is easy.

Up to you.
