3.7ghz Phenom II X4 980 on K9A2 Platinum V1?

Hello everyone (n00b speaking...),

This is a hypothetical upgrade that I'd like to make, if possible. I've tried researching this online, but the X4 980 has only been out a month. MSI's website states that this particular board supports the 3.2ghz Phenom II X4 965, so theoretically it isn't a big ask, with both processors being 125w TDP. The reason I want the highest stock speed available is because some mysterious system instability prevents me from overclocking the CPU (via the BIOS cell menu multiplier - even to 2.8ghz; crashes instantly with Prime95), and the SB600 doesn't allow the FSB to go beyond 200mhz.

Current system -

Motherboard > K9A2 Platinum V1 (MS-7376), AM2+ socket, 790FX, SB600, BIOS v1.B (latest).

PSU > ThermalTake 550w.

CPU > 2.6ghz AMD Athlon 64-bit X2 5000+ Black Edition.

Heatsink > Thermaltake V1 CL-P0401 @ 2150rpm (replacing 1600rpm Golden Orb II that blocked DIMM slots 1 & 2).

RAM > 4X1GB Corsair DDR2 Dominator @742mhz.

GPU > Sapphire Radeon HD 3650 128-bit 512mb (planning to upgrade to 1gb 256-bit Radeon 6790 soon).

I'd really appreciate any ideas about this plan. Via-a-bull, much?

Thanks,

Ben

Have you tried an OC with an older bios?

4x1 gb will put more strain on your chipset than say 2x2 gb.

A PSU upgrade may be needed.

Have you tried OC it with all other timings set to auto and your voltages set manually?

I almost got that board myself a few years ago, but went with my Gigabyte board instead simply because of my budget (I was poorer then). Anyway, that board is suppose to be one of the better overclocking 790FX boards from that era so I think it's just your CPU. My board also has the SB 600 and I OC'd my Athlon 5000+ non BE by raising the base multiplier (FSB) and got just shy of 3.2Ghz. Your instability could be that your CPU needs more voltage, you didn't adjust your RAM settings, or you need to lower your HT Link Multiplier.

I should also add that overclocking with a Phenom II BE is different than overclocking with an Athlon X2 BE. With the Athlon, the RAM speed is determined by a divider where the CPU speed is divided by some number to obtain the RAM speed. Raising the Multiplier can change the RAM speed so having tight timings on your RAM may be causing your instability. On Phenoms, the memory controller speed is multiplied from the base speed (FSB though it's not an FSB), so raising the multiplier does not automatically change the RAM speed. Even so it's best to lower the HT link on Phenoms as well when overclocking simply for stability and the HT link is the last thing to affect performance.

Wow, 4 replies already... Thanks!

I forgot to mention that my OS is Windows 7 Ultimate 64-bit SP1. HDD is 500gb, 5400rpm.

To be honest, after all the effort I've expended trying to overclock the RAM and CPU (to no avail), I've developed an mild aversion to that practice - it's brought me nothing but frustration and disappointment, so I don't think I can be bothered with that anymore (believe me, I've tried almost everything, having researched diligently). I just want things to work straight out of the box now... I suppose I'm still a console gamer at heart, having grown up in the 16-bit era of SNES.

I'd be satisfied with last year's 5770 (128-bit, 800 shader units) if it wasn't still only £10 or so cheaper than the 6790 - essentially the same card with double the bus width, according to the review here. I have a Samsung 22" 1680 x 1050 widescreen monitor that I bought in a fire sale for £50, and I want to play (WO-)Warcraft at native resolution on Ultra settings. Also, having just replaced the CPU cooler and bought another 2 matching modules of RAM off ebay, I like the idea of 'maxxing out' this machine - or at least making it semi-future-proof for the next couple of years. Prior to yesterday, there'd been no upgrades since the system was built in April 2008.

Running the latest games on high settings isn't really important to me - the 6790 is probably overkill for what I need.

The question is - in absence of official confirmation from the MSI horse's mouth, is there any reason why the Phenom II X4 980 shouldn't work with this board? I think that any upgrage beyond what I'm planning (DDR3 ram, AM3, etc) would necessitate a new motherboard, and I'm not looking to build a new rig anytime soon. The idea of a SSD drive is also tempting, since W7 takes a while to boot up.

Regarding the DIMM slots amd power draw - I was tempted to get 2x2gb (especially with the Golden Orb II diameter clearence issue), but being slightly irrational; I have to admit that having all 4 slots full is aestheically pleasing - and I didn't want the 2 original Dominator modules to be rendered redundant.

The cost of the 980 is today equal to that of an i5-2400, at $189....; H61 based MBs compatible with the 2400 are available for as little as $59 at Newegg. (Yes, you'd need DDR3 as well)

I could not see upgrading a DDr2 (mem bandwidth handicapped)- based rig with a 980...

Interestingly, MSI says that this board (with BIOS firmware version 1.B, for Thuban support) will run a AMD II X6 Phenom 1090t, but doesn't specify whether 1100t will work - and yet there are some reliable accounts of people running the 1100t on this board without problems, which suggests that the x4 980 will probably work OK, even without MSI's official blessing.

I've decided to get the 3.3ghz x6 1100t anyway.

amazon has 1090t at 159.00

Sorry to necro, but I figured an existing thread would be a good place to ask as opposed to making an entire new one. I'm upgrading my Phenom2 X4 940 to an 1100T, but when trying to flash the BIOS on my K9A2, it simply doesn't happen. Anyone have any similar issues with Live Update 5? It will go through the entire install process, restart (flashing in windows as I don't have a floppy drive) and Live Update tells me I still have version 1.0 installed.

Questions? Comments? Concerns? Criticisms? I'll answer whatever you like, and I appreciate the help in advance.

Yeah, I'm flashing it with the 940 in. I haven't picked up the 1100T yet - wanted to make sure the old mobo was still stable. I'm attempting to flash to 1.B0, which is the newest release.

By the way, thanks for a SUPER fast response. It's greatly appreciated.

Everything was out when I did it. Both mouse and keyboard are USB, as an FYI.
I'll give it another shot this evening and let you know what happens.
