I recently purchased an AMD 2600+ barton which runs 1.93ghz and after putting it in there was a performance decrease from my previous 1800+ which is only 1.53ghz. Even after I overclocked the 2600+ to a 3000+ @ 2.14ghz. In games like counter-strike and call of duty I was only getting 20-40fps and with the 1800+ in I am getting at least 70fps. This one of the oddest problems I have had. I had it set at 333 FSB for the 2600+ and all.
AMD 2600+ barton @ 3000+
768 DDr ram @ pc2100
Syntax k7s746fx motherboard
Radeon 9800SE Softmodded @ 330/270mhz
If i'm understanding correctly, your Memory Clock (MCLK) is at 266MHz (PC2100) and your FSB is not in sync with MCLK - 333MHz/266MHz FSB/MCLK ratio, in one case. FSB and MCLK should be in sync for this system. If not, latency kills performance.
Well I never knew that. You learn something new everyday. So I have to get 333 RAM then well I was getting that for Christmas anyways. I see how that is. Thanks man. Well is there anyway around that for the time being because it is running at a 2000+ but only 1.53 same as the 1800+ clock speed at the moment but nice and cool might i add LOL.
Well I have an onboard multiplier but it it stays at 11.5 no matter what jumpers I short on the board. I have my FSB up to 154 and my RAm at 135 I think at a 10:9 Ratio. Its not running to bad. Thank god for the Radeon 9800SE softmod because otherwise I would be in big trouble. How high do you think I can clock my ram before I run into a problem?
Difficult to estimate as not all dimms at a given speed rating are created equal. But, i would try to keep in sync and stress test in order to determine the best settings for both performance and stability.
Well would their be a big problem if I were to have a FSB of 368 and ram at like 340? because I asked my dad to get me pc3000 which was 366mhz and would help overclocking speed but he already ordered the pc2700. I really dont know much about overclocking ram. Like whats a normal overclock speed that most ram can get up to. I have a stick of 256 crucial and 512 simple tech.

I would suggest running FSB and MCLK in sync in all cases as latency will present problems performance-wise.

I'm not familiar with these two memory modules therefore i can't provide a *good* estimate for their ability to overclock. Nor could I provide a *good* estimate for all memory modules. All i can say is that all memory modules can at least be overclocked to some degree. The only way to really know what they're capable of is to put them to the test.
Well thanks.. It just stinks because it lowers my cpu speed a great amount for me since my onboard multiplier doenst work correctly. I am going to play around with that. I emailed the company. They have yet to respond. Well thanks man.
