Default Re: Need some help getting to 2.8GHz with my A64 x2 4800.

2.9v for your ram?? Whats your ram suppose to be running at. 2.9v seems like a lot unless DDR ram runs off high voltages.

Try Lowering your HT to 3x, try increasing your ram latencies. Try setting ram to
2t instead of 1t. Try lowering your ram speed.
Thanks for the quick replies guys.

About the ram voltages, yeah might seem a bit much to be putting it to 2.9v but i did it gradually cause i was trying to get prime stable. I think the stock voltage for my ram is 2.6. I have no need to reduce the HT multi cause when hitting 2.75GHz the ht bus is just on the 1000 mark, so i don't think that would cause instability... Unless you think so?

Havent really tried much at lowering the ram speed (timings) but have set it at 3-4-4-12 2t before with my A 3700+ and didnt do much. Do you have timings you suggest i try?

If you can, I would try dropping the memory divider and the HTT multiplier. You can put them below the rated settings aka HTT under 1000, and ram under whatever they are. So if ram is pc3200, make sure it is at least 400 or below. This will take the bottleneck off of these components, and will help to test to make sure that they aren't contributing.

It might be that you CPU simply can't do over 2.7, no matter what you try. I can't get my FX-60 over 2.9 stable, even with max voltage on the processor.
My ram is under 200Mhz at the moment according to CPU-Z. It's at 184Mhz. Would i need to lower it? I just don't want to slow my ram down to a crawl. I have it at ddr333 now. Should i try 266?

I really hope this isnt the limit! I have seen so much more potential with the 4800, why can't i get to 2.8 like everyone else Hopefully i will!!
