Memory Stress Testing
Our memory stress test measures the ability of the ASRock 939Dual to operate at its officially supported memory frequency (400MHz DDR), at the lowest memory timings that OCZ PC3200 Platinum Rev. 2 modules will support. All DIMMs used for stress testing were 512MB double-sided (or double-bank) memory. To make sure that memory performed properly in Dual-Channel mode, memory was only tested using either one dual-channel (2 DIMMs) or 2 dual-channels (4 DIMMs).We had established in our initial reviews of the ULi chipset that the best memory performance was achieved at a tRAS setting of 10T with this chipset. Therefore, all testing used the best performing 2-2-2-10 settings.
| Stable DDR400 Timings - One Dual-Channel (2/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 10T |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
Using two DIMMs in Dual-Channel 128-bit mode, the memory performed in all benchmarks at the fastest 2-2-2-10 timings at default voltage.
| Stable DDR400 Timings – 4 DIMMs (4/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 10T |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
Tests with all four DIMM slots populated on the ASRock 939Dual-SATA2 required a 2T Command Rate with 4 DIMMs in two dual channels. This is the pattern seen on every other top-performing Socket 939 board. This performance is completely competitive with the best that we have seen on nForce4 motherboards for Socket 939. It needs to be pointed out, however, that cold boot problems increased significantly when running 4 DIMMs. The cold boot issue may be as simple as a revised BIOS to support Samsung TCCD better on this board. Whatever the solution, solving the cold boot issue is a must for ASRock.

I purchased this board about two weeks ago, and have been happy ever since. I have not had any of the boot problems that anandtech had. When I get home I can check my BIOS version (that is, if anyone is interested)Pete84 - Wednesday, September 7, 2005 - link
The new southbridge that ULi is going to release is supposedly a pin for pin replacement for the 1567, and as it'll have SATA-II and more advanced raid functions etc, IF I get a crossover board that'll be the one.Furen - Wednesday, September 7, 2005 - link
I was under the impression that the new southbridge would be PCI-e only, though...Calin - Wednesday, September 7, 2005 - link
I'd say the AGP/PCIe is in the northbridge, not in the southbridge.Wesley Fink - Wednesday, September 7, 2005 - link
The PCIe is in the Northbridge on ULi chipsets, but the AGP is a M1567 Southbridge feature. If you combine a different Southbridge with the M1695 Northbridge you will not have AGP. You may want to take a closer look at the ULi chipset diagrams we published at http://www.anandtech.com/mb/showdoc.aspx?i=2471&am...">http://www.anandtech.com/mb/showdoc.aspx?i=2471&am...Fam Money - Wednesday, September 7, 2005 - link
This is the best review of a product I've wanted to purchse, you tested everything I needed you to. The only downside is it came out 22 hours after I bought the mobo.;)I feel a lot better now about getting this board and buying another gig of Patriot XBLs for it.
Thanks for the review.

I've read that this motherboard only allows 1.55v on 130nm chips, 1.45v on single-core 90nm and 1.35v on dual-core. This is probably to protect the CPU's VRMs but it should be pointed out.Wesley Fink - Wednesday, September 7, 2005 - link
We did check that an X2 operated on the ASRock, but we did not check to see if the voltage adjustments shifted. I tried a 4800+ x2 again, which has a default voltage of 1.35V, and the voltage adjustments now top out at 1.40v. It appears the slding voltage adjustments set themselves to .05v more than the voltage specification. A wider range at the top would definitely be better fro many users.I will add this information to the review.

If they can fix their boot issues, this board is perfect for people like me who have a decent office computer (P4 2.0, 756 megs) and who would like to do a little gaming now, and more down the road. This board would allow me to take advantage of any great AGP deal that came along and add it to my current system, play some previous generation games, and then later keep my GPU and upgrade to a much desired A64 system when I have more time/money.

Like I said. I have a asrock that has video problems and ram issues. I have talked to others with the same problem yet Asrock has done nothign and does not respond to anybody. So I would not buy it until you hear soemthing else or you will be like myself and other Asrock owners hopeing and waiting. Mind you the boards are cheap, but the basic stuff should still work
