X48 Rampage Formula Preview.

Cant resist asking the following question.

From the M/B Specs that i Google found the following
In an effort to eventually get rid of the conventional IDE ATA standard, the X38 chipset removes IDE support altogether. Despite this, the Maximus Formula ships with a single IDE port thanks to the use of the JMicron JMB368 PATA controller. The ICH9R south bridge offers up to six Serial II ATA ports, boasting data transfer rates of up to 300MB/s. Intel also offers RAID functions for these four SATA ports, supporting RAID 0 for performance and RAID 1 for protection, along with RAID 5 and RAID10. Advanced Host Controller Interface (AHCI) further boosts performance with Native Command Queuing (NCQ), and provides native hot plug for drive swaps.

Now
If the drives them selfs supporting 3Gb/s speed and the MotherBoard it self does the same, Why are is the speed result lower that that?
I know n00b question.. but here you have it.

Just because the drives use the 3Gb/s data connection doesn't mean that it's going to be able to read and copy at those speeds.

I need some help with my new memory. I recently bought a set 2 x 2GB Mushkin XP2-8500 (996599). And dont know what would be best for performance. Currently running 9x400 with mem @ 533Mhz 5-5-5-15 but with a 3:4 divider.
My CPU is a soon to be replaced E6850 @ 3,6Ghz/ (3,7Ghz capable). So I can also choose to run them at 8x450 with 1:1 and then try to lower timings and PL, or again with a divider and try to OC the memory. Anyone any idea what would be fastest? Or anyone with other useful tips regarding this memory if I choose to OC? Cant find a lot of users here on XS.
Tnx in advance.

Why not 8 X 450MHz and DDR 1081MHz with tRD 7?

Ok right now put it at 8x460 with my memory @ 1105Mhz 5-5-5-15. Static read enabled, clock twister moderate, PL 9. Running Windows mem test for stability, hope it holds.
Would it be a big help to switch to bios 0803? I'm still on 0410.

Edit:
Ok seems to be stable, of course no big OC but all bits help. Wouldnt 1200Mhz be possible with this mem and lower timings? Can't find any results.

Why do you use PL 9 and not PL 7?

Take a look at Everest Cache Latency & BW at PL9, this should put memory read bandwidth around 5-700mb/s slower than memory write bandwidth correct?

If so you can safely tighten down to PL8, which should close the gap to 2-400mb/sec, and probably not require any additional Vnb, or if so very little. PL7 at that FSB will need too much more Vnb, and too tight of a PL sucks for everyday usage anyway. Stability changes with the weather. One day its too warm and the thing crashes randomly, then you get a cool day and it runs perfect.

Not worth the hassle IMO, it's great for benching but other than that for my every day usage I normally use the next PL lower than the one that gives roughly equal Memory Read and Write bandwidth, which at 460FSB will be PL8. PL7 will give roughly equal read/write, and require a good 0.05-0.10v more on Vnb for consistent stability.

Now personally I've run PL7 at 481FSB on this board, but I was using near 1.53v Vnb and even with this much, sometimes from boot to boot it would be hit and miss. No amount of voltage or fine tuning can fix this period. I ended up dropping down to PL8 because I could run it at 1.47v without it missing a beat. Mind you it would post and even pass stress tests at 1.41v without ever getting an error, but when it came down to real world usage such as long gaming sessions or 24/7 uptime, i needed that extra 0.06v or so to keep the thing from BSOD'ing, leaking memory or just plain old crashing apps randomly. Was it worth the extra 300mb/sec read bandwidth to have it crash after 2 hours of gaming or in the middle of watching a movie, absolutely not. If anything my system actually responded much better from loading up windows, to opening or closing apps, with a slacker Performance Level. PL9 was a bit too slack, and made things no better than PL7.

So to sum it up, don't listen to these clowns when they say a tight PL is the way to go, because they also are the same ones saying they get errors in prime or linpack on settings that were previously stable, and the same ones who won't accept that settings or voltages are too tight or too low to be the problem

Just find the Performance Level that gives you both responsiveness and stability. Try PL9 and PL8, and test both stressing and everyday usage, take note of how windows boots up, time to display icons, load apps, etc. See which of the two suits your settings.

Euhmm... I don't think that 8 X 450MHz and tRD 7 takes a lot of voltage on the NB and that's what I suggested. I didn't say 8 X 460MHz or anything else.

You forgot to say that these "clowns" use other memory now.

Ok Tnx for the advice, I also thought PL7 to be a bit tight on these speeds but it all seems to be very stable. So I did the everest Benchmark and my read/write bandwidth were 9440/8443. So my Read is actually faster instead of slower. What would be best in my situation?
Also thinking of setting other divider so I can try the 1200Mhz setting, dunno if the mem will hold though, will have to see.

And this is based on what?
