Question for new memory P5E3 Deluxe/Wifi


LAZar0

Recommended Posts

Hi!,

 

I am thinking to buy a TW3X4G1800C8DF kit of RAM for a P5E3 Deluxe/Wifi, QX9770 and HD4870x2.

 

I like to know if I could get running the 4Gb at 1600Mhz (maybe more?) and what latencies could I reach with this memory modules STABLE with this combination of hardware. The default values (8-8-8-24) could be reached easy (maybe 7-7-7-20) at 1600Mhz?

 

Thanks in advance.

People have had much trouble gettting high end DRAM speeds out of this board.

 

Here's a thread for you to read regarding this board.

I would personally go for 1600C7 or 1600C9. You will need a 450Mhz FSB to attain 1800Mhz on the DRAM and that's pretty high for that CPU. 400 X 10 and 1600Mhz on the DRAM is where I would try for, but understand, there are more than a few having issues trying to get more than 1333 on this board.

Thank you, DerekT,

 

I thought that using 1800Mhz memory was much easier to get 1600Mhz than 1600Mhz memory itself.

 

Although, if there are so problems with this board at 1600Mhz, maybe it is better to get a Rampage Extreme or P5E3 Premium in this case, but for now I don't want to spend more money on another mobo.

 

The 1600C7 you mentioned is a 4Gb kit?

Even the Rampage Extreme is having issues with getting the high end overclocks and high end DRAM to marry. If I were you, I would choose the Q9650 and some good 1600C9Mhz DDR3 memory and clock them both up. The difference between C7 and C9 with the Intel Core2 tech is not marked at all. You can very likely tighten the timings up or raise the bandwidth as well, when you overclock the CPU.

 

400 X 9 = 3.6Ghz is an easy overclock for the Q9650 and 1600C9 will give you a very fast system.

1600C7 is over 400.00 and the 1600C9 is 185.00. Clearly the C9 is the best buy especially considering Intel Core 2 likes bandwidth more than timings. I have tested this many times. I have also tested 1600C7 and 1600C9.

 

This will run as fast as a QX9770. With both overclocked to 3.6Ghz they will both run the same. The QX9770 is really pretty much a waste of money unless you are going with high end water cooling or more advanced extreme cooling methods. For air cooling, it is, in my opinion, throwing money away.

 

Regarding the stability of the board. You stand a far better chance at running with 9 X 400 = 3.6Ghz and 1600Mhz on the DRAM as a 1:1 ratio than you do with other ratios. The Intel Spec ratio seems to work the most stably without much tweaking.

 

Are you looking for high end FSB overclocks with high end cooling?

 

So, unless you are looking for high end overclocks, then this is the way I would go. Considering that the difference in performance with Core 2 Quad at 3.6Ghz and 1600Mhz on the DRAM vs Core 2 Quad at 4.0Ghz with 1800Mhz on the DRAM is not that great in reality. Yes, canned bandwidth and CPU benchmarks will show a difference, but there will not be a marked difference in real time instruction working.
