E2180 help

[blipblop]

Alright, this is my first shot at this.

I have read at 1:1 timings are the best, so that is what I am at.

My multiplier is 10 x 280 Mhz meaning I am at 2.8Ghz.

My question is this my DRAM frequency is only 280Mhz, but my RAM is rated faster than this. Am I running slower than I have to?

I have a Gigabyte EP35-dsl3 board.

Everything else is stock and I am currently running Prime95 on it and for the past hour it has been stable.

Can I keep it like this? Or should I run my RAM at its rated speed?

I have DDR2 4GB (2X2GB) PC6400 DUAL / TWIN2X4096-6400C5DHX CORSAIR as my memory.

Sorry if my post is all over the place. Thanks

Well, there's not really any benefit to running RAM faster than 1:1, which in your case would be DDR2-560. Since you have DDR2-800, you could use one of the different RAM dividers to adjust your RAM so that it's running faster than 560. Performance-wise, I really doubt that you would notice it though.

If you really wanted to push things, you might try going for 400 x 8, which with a 1:1 ratio, would run your memory at DDR2-800. That's what I'm running with my E2140s.

I've got basically the same setup and I just started to OC and was wondering the same thing.

GA-EP35-DS3L
E2180
2x2GB Super Talent PC6400

Right now I'm only up to 2.3GHz (10x230) and 1:1 timing. I'm starting it off slow to make sure everything is 100% stable as I go up.

Blipblop, what are you running for voltages out of curiosity?

I also noticed that even though I have my VCore set to 1.350, CPU-Z still reports it at 1.295 and it drops to 1.280 during stress tests. Even when it was VCore at stock 1.325 CPU-Z reported 1.295.
Is there a reason it's not going up?

If its 100% stable its really up to you...you should be able to bring it prtty close to 800 if you want, although you most likely wont notice, 1:1 is a great way to start an overclock, but if your going for a full system OC you can move beyond this when you feel that your CPU is stable

Whenever I help a friend with a OC we always start at 1:1, but I believe that the CPU is still half the OC, and although the RAM difference may only be noticed in synthetic benchmarks, I still believe that it is an important part of the OC. But RAM is always secondary to the CPU. Keeping it at the low freq (less voltage) will produce less heat (still not very noticeable), but a higher freq will be better for synthetic benchmarks, and maybe 1 or 2 seconds for some random program but its still there.

Also what CPU do you have there? EDIT: sometimes I don't even think

you've entered the wonderful world of vdroop, and that is some prtty serous vdroop too

basically to protect the computer there will be a resistor that will reduce the amount of voltage to the CPU in case of fluctuationation, one from BIOS to OS and one during load

You can do a pencil mod, although there will be people who will tell you that is a bad move, its purely up to you. I have had a pencil mod on my P5K for about 6 months without an issue, it is completely removable with alcohol and it reduced my vdroop from 0.08v from BIOS to OS and 0.03v during load to 0.01v from BIOS to OS and 0 during load. Although this is something you must do at your own risk!!!, I have not had a problem with it (my logic is if i does break that means an excuse for a P45 board so its ok) but it is something you should do research into.
