Gigabyte K8NXP-SLI: Overclocking and Stress Testing
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | |
| Gigabyte K8NXP-SLI | |
| Processor: | Athlon 64 4000+ (2.4GHz, 1MB Cache) |
| CPU Voltage: | 1.55V (default 1.50V) |
| Cooling: | Thermaltake Silent Boost K8 Heat sink/Fan |
| Power Supply: | OCZ Power Stream 520W |
| Memory: | OCZ PC3200 EL Platinum Rev. 2 (Samsung TCCD Memory Chips) |
| Hard Drive: | Seagate 120GB 7200RPM SATA 8MB Cache |
| Maximum OC: (Standard Ratio) |
230x12 (4X HT, 2.5-3-2-7, 1T, 2.8V) 2760MHz (+15%) |
| Maximum FSB: (Lower Ratio) |
230x12 (2760MHz) (4X HT, 2.5-3-2-7, 2.8V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+15% Bus Overclock) |
After the excellent overclocking results that we found in our pre-production review of the K8NXP-SLI, we really expected the Gigabyte SLI to be near the top of our overclocking charts. However, something has happened along the way from pre-production to production because our production board could only reach a very disappointing 230 CPU speed regardless of the multiplier selected. This is in stark contrast to the 284 that we easily reached on the pre-production board.
We recently met with Gigabyte to discuss this issue and Gigabyte has assured us that they will make updates to get overclocking back to the levels which we saw in our earlier review. For now, we can only say that we have no idea what you will actually find in the overclocking capabilities of a K8NXP-SLI that you might buy. It could be stellar, like the pre-production board that we tested, or mediocre, like the last board that we tested. We have evidence to support either conclusion.
Memory Stress Test Results:
Our memory stress tests measure the ability of the K8NXP-SLI 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).| Stable DDR400 Timings - One Dual-Channel (2/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 7T |
| Precharge Delay: | 2T |
| Command Rate: | 1T |
Using two DIMMs in Dual-Channel 128-bit mode, the memory performed in all benchmarks at the fastest 2-2-2-7 timings, at default 2.6 voltage.
Tests with 4 DS DIMMs on an AMD Athlon 64 system are more demanding, since AMD specifies DDR333 for this combination. However, most AMD Athlon 64 motherboards combined with recent AMD processors (the memory controller is on the AMD CPU) have been able to handle 4 DIMMs at DDR400.
| Stable DDR400 Timings - 4 DIMMs (4/4 DIMMs populated) |
|
| Clock Speed: | 200MHz |
| CAS Latency: | 2.0 |
| RAS to CAS Delay: | 2T |
| RAS Precharge: | 7T |
| Precharge Delay: | 2T |
| Command Rate: | 2T |
Tests with all four DIMM slots populated on the Gigabyte required a 2T Command Rate with 4 DIMMs in two dual channels. This is the pattern seen on other top-performing Socket 939 boards. There was no problem running 4 DS DIMMs at DDR400 at the same aggressive 2-2-2-7 settings, which worked well with 2 DIMMs.

If i was a doubting type I would suggest that Nvidia spent as much time tuning their drivers for benchmarks as they do games.Nice to see support for some unreleased games such as Battlefield 2 on the list though.
Wesley, you get my email btw? (sorry for bugging you)?

I've done some further testing, and still no luck. The PCStats review also indicated 192Khz output, but I can't find that either. I'm still hoping for something, and will let you guys know if anything comes up.Other points:
+ The onboard Creative can attenuate the digital outputs just like a regular live could. Most onboard solutions that i have used could not
- Cannot have Analog and Digital outs enabled at the same time (at least I haven't found that yet). All other onboard solutions that I have tried were able to do this. An example of what I'd like to do (ideally) is have my Zalman Real Surround headphones plugged in to the analog ports, and the z5500's plugged into the digital (coax/optical). When the GF complains, I could turn the z5500's off, and put on the headphones. With creative you do this BUT you also have to uncheck the digital out only box. If they can bot h be enabled at the same time, let me know (Y)
- Either the Z5500's can't accept 96/24 on the optical in, or the creative isn't outputting 96/24 on the optical out.
- Only Coax or Optical work at one time (with the Z5500's)
- DD and DTS passthroughs work with Videolan and DVD's/.ts's.
I'll try this board for a while longer, but if encode will not work, I'll be heading to DFI. It's a bit more expensive, but you get the Lan Tote (woohhoo!) and the extra PCIx slots. Anyone have any comments on DFI's onboard sound?

Thanks giz02. One of these days some manufacturer is going to realize there's demand for this and meet it... I just hope that day comes sooner than later.SLK75 - Tuesday, March 1, 2005 - link
I bought the GA-K8NXP-9 because fo the rave reviews on its OC abilities which Anandtech also proved in their pre-production sample reviewed towards the end of last year...All of a sudden now Gigabyte's production version of the board does not seem to clock high as was expected and proved previously WHYYYY ???? and Anandtech make it really clear to Gigabyte that people went and bought their board not only first its great features but also for its OC capabilities...I hope Gigabyte can address this with a new BIOSgiz02 - Tuesday, March 1, 2005 - link
I feel DUPED by that PCSTATS review. I've asked the reviewer for why he indicated that the board can DICE (either how to do it, or who told him it was possible).The board is .... OK...
I'da rather had the DFI (if DICE is not possible!)

#89 - looks like we'll both still wait for the next SoundStorm. Maybe the next gen of PCI-E sound cards will have DDL?bob661 - Tuesday, March 1, 2005 - link
#89Thanks for the test.
giz02 - Tuesday, March 1, 2005 - link
So far, It's a negative on the DICE :(I have a single coax cable connected from the onboard card to my Z-5500's and they are not recieving Dolby on the speaker tests. Left and Right channels come through but that is is... 96-24 is working as well, but zilch on the 5.1 :(

#87: AMD has NOT made it clear that ECC is an Opteron only feature. Read the document from the link I posted. As for ASUS not supporting ECC, download the manual and look at pages 4-21 and 4-22. In the screenshot for DRAM configuration there is an item for ECC enablement. The ASUS K8N-E deluxe (socket 754) also supports ECC. If you still have doubts that the Athlon 64 supports ECC, go to crucial.com and see what memory is supported by the ASUS K8N-E deluxe and A8N-SLI deluxe. I think that you might be confusing registered memory with ECC. If you write code work with critical data ECC is worth having. I have had bad memory in the past that corrupted data without crashing the machine. Considering misinformation that is sometimes provided by motherboard manufacturers and your obvious confusion about the Athlon 64, I think that ECC deserves some mention by motherboard reviewers. I myself would like to understand why the A8N-SLI apparently supports 4 256MB ECC memory modules but not 2 512MB ECC memory modules (page 2-12 in manual), Wesley?
