AOpen AK89 Max: From Ugly Duckling to Swan

AOpen AK89 Max: BIOS
The AK89 Max uses Award BIOS with a layout that will be familiar to most users. AOpen also includes a full set of tweak options, generally located under the Advanced Chipset Features and Frequency/Voltage Control tabs.
Advanced Chipset Features has submenus for Dram and Hypertransport timings.
AOpen provides a very complete selection of memory timing adjustments in the Dram submenu.
There are also settings to adjust HT frequency. This becomes very important in extreme overclocking. While we were surprised to see a 4X option (the 150 is specified as 600HT), we did not find the 4X setting very stable or useful.
Frequency and Voltage adjustments are in this submenu.
This includes FSB and Ratios below the CPU default. While the FSB range is only to a disappointing 250, we found ways around this as you will see in our Extreme Overclocking report.
The vDIMM range to 2.8V is acceptable, but we would have preferred settings to 3.0V to 3.1V.
The CPU voltage can only be adjusted to a very disappointing 1.55V. To be fair, we have not seen higher vcores do much to increase overclocking on Athlon 64 processors, but those who use water or phase-change cooling will want a much higher range at the top.
Probably the one thing that we have most wished for on nForce3-150 boards is a working AGP lock. In this case, the adjustments are there from 66.67 to 100 in 1 MHz increments. More important, with BIOS version 1.06M, the PCI/AGP lock really works on this board. How do we know? How about a maximum overclock of 347 with a multiplier of 6.0?

Am I the only one that found this artcle hard to follow ? Its all over the place ... What the hell was being tested ?cowdog - Thursday, April 22, 2004 - link
Thanks for the information.BTW, I finally did get through to AOpen, and they have been very prompt and helpful. I must have fallen through the cracks or something earlier.

Cowdog -I used our standard Mushkin/OCZ 3500 at default speed. Above 233, I used OCZ 3500EB to DDR500, and OCZ 4200EL to DDR550. if you look closely at the screen shots the memory is identified on the overclocks. As you state, BH6 can't reach these levels.
AOpen tells us the board would require a revision to allow an increase in vcore, and with the nF3-250 near, a new rev will not appear with the 150. They can't modify the vCore on this board with just a BIOS update. vdimm and higher FSB may be a possibility - we have requested those changes - but it is more likely these will come with the 250 version.

FYI: This seemed as good a place to post this as anywhere else. Just came across a new bios, 1.07"For AMD recommended,memory clock will set to DDR333 when DIMM1 and DIMM2 plugged double side DDR400 memory."
Two things:
1. BIOS defaulted to 200x11 for me, which isn't a good thing for an A64 3200
2. I have no option for DDR400 in the bios with 2x246MB Mushkin Lv II PC3500.
3. When I tried to lower the multipler, the bios gave me an error at POST (safe mode or something like that). Then even if I selected bios defaults I had the same message. I reset cmos and it worked, although cpu frequency went back to the 200x11.
Might want to be leary of bios 1.07, although my system may simply be whacked.

Wesley, I must admit that I haven't tried Dr. AOpen; I missed that. I did fill out their tech support form (with serial number, etc.) three times. This third time (last night) I did receive an automated reply for the first time. I kept screen shots of the previous forms, and I know my email was right. I'm not sure what happened. Anyway, I'll try Dr. AOpen as well, thanks.Couple of things to add:
1. As far back as the official 1.06 bios, I was able to change multiplers (only downward, of course) using Clockgen. I found that clockgen would work if I set the multiplier lower in the bios, even though that did not change the multiplier at post. 1.06 m bios now changes the multiplier at post, as you note. Funny thing too, after I updated to 1.06m, the default multipler was 4.
2. I don't understand why AOpen won't open up the cpu and dimm voltages as they did with the AK86-L. As you note, the AK89 Max is their current A64 flagship. Why add features via bios update to the AK86-L but not do similar for the AK89 Max? Unless, of course, those features can't be added with a bios update. Do you know?
3. When you overlclocked the memory 1:1 to 250Mhz, were you using the OCZ or Mushkin memory that you referenced earlier in the article? I am unable run some Mushkin BH-5 memory 1:1 at anything higher than 230Mhz (clockgen) and 210Mhz (bios) with the multiplier way down and LDT at 3 or 2.5 even though I can run the same memory at speeds higher than 250Mz on another board. Same thing with some Corsair LL v.1.1 memory. Just curious. Perhaps the cpu is the limiting factor; is there that much variability?
Anyway, thanks for a really nice and thorough review. I am trying very hard to like this board (and AOpen) and your review renewed my motivation.

#7 - The Asus K8V is based on the VIA K8T800 chipset which has no capability at all for a PCI/AGP lock. We have found the performance of the VIA and nForce3-150 to be about the same at stock speed, but the VIA is simply not cpable of avchieving the overclocks we have reported in this review.The K8V performs about like the MSI K8V Neo which is included in our benchmarks.

I wish you would have done some comparisons with the ASUS K8V Deluxe as well, as this seems to be quite a popular board for Athlon64 machines (plus, I'm thinking about using it for my next build...). Oh well...Wesley Fink - Wednesday, April 21, 2004 - link
#5 - Have you tried Dr. AOpen on line? If nothing has worked please email me your details and I will forward your email to contacts at AOpen.Both Evan Lieb and I have had very positive Support expereinces with AOpen. If others are getting different treatment it is important to know that and report it in our reviews.

is this a Real AGP /PCI lock ???i heard there way to mod the bios to lock but not the same as hardware Agp/pci locks
well something like a sofmod ill see if i can find the link
may be a this must buy board i got a via KT800
i can do 3000+ 10 X 250= 2500MHZ but my radeon 9800pro & audigy bitch they say to high =) PCI: 41 APG: 83

2-I was quite impressed by te FSB's the AOpen was able to hit and did feel the review was there just to show what the board is capable of.I also have this board and i would say 1:1 will be pretty limited due to 2.8V vdimm max.
Also it was nice to see a comparison of 3dmark although i know this is not a bench Wes uses.
Overall i think the review showed the board has awesome potential and proved that boards can become awesome with a "tuned" bios ;-)
