Upgraded from GTX460 to GTX660

Lemme list out the specs of my PC

Operating System : Microsoft Windows 7 Professional 32-bit SP1

CPU : Intel Core i7 2600 @ 3.40GHz
Sandy Bridge 32nm Technology

RAM : 4.00 GB Single-Channel DDR3 @ 665MHz (9-9-9-24)

Motherboard : Gigabyte Technology Co., Ltd. P61A-D3 (Intel Core i7-2600 CPU @ 3.40GHz)

Graphics : 1023MB GeForce GTX 460 (Gigabyte)

So I am upgrading to a GTX660 ASUS. With the help of my uncle, right after we pop the guy in, my PC just wouldn't start, as in the BIOS startup won't even appear and it makes a 3 beeping sound. Putting back the GTX460 makes everything okay again.

We ruled out lack of power supply to the GPU already by disconnecting the power sockets to the HDDs.

I'm postulating that the motherboard might not be compatible with the GPU but that is highly unlikely.

So what do you guys think? I'm at a lost here

  1. What are the specs of your power supply? You can read them off the sticker on it, if you don't know the make or model.

    The fact that a GTX660 has a lower power draw than a GTX460 should have been enough to rule out the psu
  3. The RAM might be a problem. You're trying to use a video card that has 2GiB of VRAM (assuming gthat your model is a 2GB model) in a computer that has only 4GiB of RAM and a 32 bit OS. I think that it should work, but it might be an issue.

    Is this what you need?

    Input Voltage 110 ~ 115V / 220 ~ 230V
    Input Current 8A@115Vac / 6.3A@230Vac

    EDIT: Also this is the link to my PSU http://www.coolermaster.com/product.php?product_id=5888
  5. it was what was under the one or two 12v that we needed........ amperage. 32 if that's the right ps you listed. kinda light........ did you plug the 2 power connectors into your video card ?

    The 12V amperage should be high enough, especially if it works with a GTX 460, but that PSU is not from a very reliable brand and it might actually be the problem in a different way as a result of that.

    22 amps on the 12V rail would be enough for the GTX 660 Ti so long as the CPU isn't a huge power hog and there aren't other abnormally high power-consumption components. 32 amps should be much more than enough.

    Not a very good psu, but if it runs your GTX460 without a problem there's no way it wouldn't run a lower power card
  9. So I think it is safe to say that the PSU do not have any relation to my problem here. Never had this much problem upgrading a GPU before lol
  10. there are people out there that get bad cards. you might want to consider rma-ing........... if you do, put a hidden mark on it so they don't send the same one back. ( magic marker )

    I guess I'll try this

    I would love to see the proof of this, because every review I see has the GTX 660 sucking about 20W more than a 460 while playing a taxing game

    because it's actually comparing apples to oranges, they're probably closer to equal power draw
  13. Show us some reviews of the 140 watt rated card using more power than the 160 watt rated card

    you tell me - exactly where you're getting these numbers from???
  15. Didn't think so

    look delloser1 - you're the one stating the cards have a certain power draw - it's a very simple question - show me where you got that information is all
  17. The reference 660 Ti uses slightly less power than the reference 670. Anyone who says otherwise has no experience with the card. It's nearly identical to the 670 with the same GPU at the same frequencies and the same number of memory chips at the same frequency. The main difference is that one of the memory controllers (and related hardware such as the ROPs that are a part of that memory controller) are disabled and the two extra memory chips are instead controlled by one of the remaining memory controllers (one controller has 1GiB of VRAM and the other two have .5GiB each).

    If the PSU is not working with the 660 Ti, then it would have had to degraded greatly since you bought it. It is a mere Cooler Master PSU, so that's entirely possible, but that the card is DOA is more likely.

    I Mistook 660 Ti for the regular 660 and you missed that, so you're no less noobish than I was for my mistake. Regardless of that, Guru3D's power consumption numbers are useless and their site specifically states several reasons for why that is. Still, yes, maybe the regular 660 should use less power than the 460.

    The regular 660 uses much less power than the 660 Ti. It has a much smaller GPU with about 29% fewer cores and a lower clock frequency IIRC.

    Wasn't directed at you :non:

    1 it's a Ti
    2 it's a different platform measuring under a different scenario

    OK, my bad.
  23. delluser1 said:

    ok, my bad on the card difference - but it's a real world scenario and not some benchmark that is pointless, which is exactly how the OP's computer is going to react while playing (likely) the same games

    Had to run for the phone sry
    Wanted to address your concern
    Yes the numbers are subjective, it's the fact that those numbers are measured on the same system with the same power supply that make's them relevant

    OP's system won't even start with the card
    Keep trying though

    ok... perhaps you're not aware of something called in-rush current
    http://en.wikipedia.org/wiki/Inrush_current

    ... just sayin...
  27. it can only be 1 of 2 things - a bum card, or a power supply that cannot provide the necessary current to start the computer with the card in

    unless he bumped something else while plugging in and out the card - like jogging the memory or a heatsink somewhere

    the fact that the computer boots and runs normally with the original card in, points to a bum card, but you never know...
  28. pull the card/pull the memory. re-seat memory/put new card back in.
  29. OP could also try re-seating the CMOS battery.
  30. His system works fine with his old card, stop getting him to play around with things completely unrelated to a graphics card swap.

    Also, this has to be the longest, and most useless discussion I have ever read on an obvious DOA card. /slowclap
  31. "my PC just wouldn't start, as in the BIOS startup won't even appear and it makes a 3 beeping sound"

    --> anyone converted this error code into english (quick scan of manual and I can't see anything) ?
  32. If I remember correctly, three beeps is often a memory or PSU problem, but different boards can have different codes.

    "A memory failure has occurred in the first 64K of RAM" - as a quick check, try swapping your memory modules. If the 660 allows boot into windows..........


    Replace all your memory (I know, you can trouble shoot more but it may be easier for you not to)

    that's why I posted this above....... miss it ?

    It's called re-inforcing a (i.e. your) point - no offence intended! :D

    Also, note qualification in both links - always better for any OP since they then start to believe and/or take notice.
  36. sometimes things are better left unsaid............. no offense intended.
  37. WOAH look at all these replies!

    Apparently the motherboard is dead lol, not the GPU. Tried that motherboard on my other PCs and it all result in the same black screen and beeping sounds. Appreciate the response from you guys, it gave me some idea on what to do and diagnosing my problem!

    Well anyway got a new motherboard and everything is smooth ride now. Thanks everyone!
