9NDA3+ Memory Confusion

I bought a 9NDA3+, A64 3500+ (Winchester) and Thermalright XP90 last week plus a pair of Patriot 3200 XBLK 512Mb DDR Modules (a Dual Channel matched kit). However if I try and run the memory at even 1MHz above 200MHz the system locks up on the BIOS screen 7 times out of 10 and I get memory errors (even at 2.8v, 10,3,3,2 and HTT 4x or 3x - more stable in slots 3+4 but still unacceptable)

Using my old 512Mb Twinmos (BH5) 3200+ sticks I am running at 218MHz 10,3,3,2 1T with no problems (CPU @ 2400Mhz).

I'm going to send the Patriot sticks back, but am unsure what to replace them with.

My short list is:
OCZ 3200 EL Platinum Rev2
A-Data PC4800 DDR600 Vitesta
GeIL PC4400 Ultra Platinum

I'm only look for a reasonably modest overclock, about 227MHz for CPU @ 2500, stability is most important to me (and running 4 x SATA drives I've gt to be careful not to push to bus to high and loose channels 3&4).

Any thoughts/experience with any of the above? Should I be looking at other makes/Models of DDR?

What are the guaranteed timings for those mem sticks? I'm almost 100% sure they can't handle Cas Latency 2 at frequency higher than 200Mh.

This particular mobo, as some friends of mine have checked, seems to like Samsung TCCD memory chips, so :

OCZ 3200 EL Platinum Rev2 - Samsung TCCD, known to be very good overclockers.

A-Data PC4800 DDR600 Vitesta - again Samsung TCCD, don't come in matched pairs for dual channel, should do better than the OCZs though.

GeIL PC4400 Ultra Platinum - I have no idea (Google is your friend ).

G.Skill PC4400 is another make, that you should consider, but be careful and mark the differences in many versions of these sticks (guaranteed timings).

cheers

Specs from PDP's website for guaranteed performance of thePartriot sticks are:

PC3200 (400MHz) 2-2-2-5-1T 2.6-2.7v
PC3500 (436MHz) 2-3-3-6-1T 2.6-2.7v
PC3700 (466MHz) 2-3-3-6-1T 2.7-2.8v
PC4000 (500MHz) 2.5-3-3-7-1T 2.75-2.8v
PC4200 (533MHz) 3-4-4-8-1T 2.85-2.95v

I was attempting 436MHz(218) 10-3-3-2 1T @ 2.8v so was well within spec.

At the moment I errings toward the A-Data, but can't find anyone with any stock - awaiting info on lead times.

I read elsewhere that the G.Skill need more volts than this mobo can provide (without modding) which is why I haven't short-listed them at this stage. Does anyone have any experience of running these at 2.8v (or lower)?

Well, in fact they need less volts than you think :

as all Samsung TCCD chips (no high voltages requiered).

I've had pretty good luck with the OCZ... Once I took everything off SATA 3 and 4... They gave me terrible trouble...

I've now got up to 225MHz HTT with the Twinmos sticks (see updated sig). I think that this is their max without voltage mod, hence my search for new ram.

WooferWrecker: At what HTT did SATA 3&4 start causing you problems? I've got 4 SATA drives on my system so want to know limits of the controller. No point spending out on new ram if it's going to cause me HDD problems.

I've now read several conflicting posts/reports on whether its best to stick with max CPU multiplier/low DDR latencies or push for higher HTT with lower multiplier/looser timings. Many say CPU multiplier has max impact on performance, but then others indicate higher HTT frequencies are the way to go (high 200's to 300+) - I'm even more confused than when I started this thread on that score. Please help!!

you will gain more if you can overclock your ram much higher (at the cost of less agressive latencies)

My 3500+ Newcastle can go only to a 2530-2570 Mhz without starting to bug.
I ve done lots of differents bench to see what was the best setting with my pair of Twinx PC4400C25. Here is some results:

2570Mhz: 3500+ @ 10*257, 2.5-4-4-8 1T, HTT*4
Cpumark99= 292-294
Everest memory bench: read= 6445, write=2875, latency=48.3

2565Mhz: 3500+ @ 9*285, 2.5-4-4-8 1T, HTT*3
Cpumark99= 292-294
Everest memory bench: read= 6914, write=3105, latency=44.2


I think that the limit of a 3500+ 0.09µ is near 2750. So, the best for you will be to reach this limit with 10*275 or 9*305 (with really good ram).
Unfortunately, you will be unable to do that if you are using the SATA 3&4 controller because they are not locked at 33Mhz. In your case, with 4 SATA HDD, if you want to overclock, you will have to buy a PCI SATA controler card.

Hi Timelord,

I personally found that I couldn't run above 210 FSB, regardless of what HT multiplier was set too...

jlccarv was the man who clued me into the problem with ports 3 and 4.

But it seems that all boards are different, as you are able to run at 225 MHz on ports 3 and 4...

Have you tried taking your drives off of them just to see what sort of results you get?

I need access to all four drives, so no. However I've ordered a 4-port SATA PCI card today so I'll be prepared for when my replacement RAM arrives. I'm waiting for the shop to advise lead-in time on the A-Data before making a final decision.

It seems to be the tolerance of the drives attached to the semi-unlocked bus that improves their max FSB ability. Certain drives one thing, others another - looks like we're on a Maxtor versus Western Digital thing in the same way that I can do 230FSB with an NVidia PCIe card and 260FSB on an ATi PCIe card on a 5EPA+.
