AYHJA quick question?

[ozzy0627]

Will ayhja be posted on the outside of the chip along with the version like ayhja y...........and how many differnt versions our their? is their like a ayhja x , a, b ..........etc...??

[train22]

it will be printed on the core, and there are only a few types you should be looking for, that's a R and a Y.

In fact I just looked through a person asking a similar question, look ath the diagram..

I, unfortunately got a 1.33 AYHJA "9" and it is not a very spectacular overclocker. Using all the tricks I know, it tops out around 1.54Ghz. This is one to be avoided.

I've got a 1.4gig AYHJA 'Y', and although I've heard a few bad things about these (I know there's a few guys around who've had difficulty getting over 1.6gigs), mine seems to be doing ok. I'm running happily at 1600 with 1.85V, and I just got it to run 3DMark2001 at 1600, 1.8V, which it wouldn't do at all a few days ago. I'm hoping with another few days burn-in to get it rock stable at 1600 with 1.8V, then push higher.

Like all things, it's a lottery, but I'd say with a 1.4gig AYHJA 'Y' like I have you should be pretty certain of 1600 - maybe not straight away, but probably after a little burn-in. Who know, with good cooling (I'm watercooled) and more voltage (volt mod), you may get higher.

I'd like to see 1700 out of this baby with a volt mod... :D

Sounds like the AVIA "9" I got which tops out around 1420. I see most AVIA "Y" CPUs are good for 1500+. Its like "Y" is the 'bonus' code which give you an extra 100+ Mhz.

[Wega!]

I got a AXIA "9". At 1.85V it's stable at 1470MHz, I think that's ok.

My AYHJA-Y has been burning for 4 days now and it still doesn't want to stabilize at 1600. I can boot to 1600 but fail the burnin tests or SETI as soon as I start it. (This is at 1.85v) I'm hoping to do the voltage mod but am scared to mess somthing up.

Has anyone heard of the ability to raise your voltage a bit by doming somhing with the L7 bridge or will that just bring me up to 1.85 max (which is what my board supports)

[Rob Cork]

Changing the L7 bridges will just change the default voltage for the cpu, which on most boards (like the KG7) will make no difference AFAIK. The only board for which I know setting the default voltage to 1.85V using the L7s helps is the Epox 8K7A. That's because that board (and the + version) adds voltage to the default vcore rather than just setting the straight vcore value. So rather than options of 1.7, 1.75, 1.8 etc, you see things like '+0.05', '+0.1' etc - up to 0.4 or something I think. So connecting the L7s to get a default of 1.85 allows you to go up to about 2.2 with that board.

However, to cut a short story long :rolleyes: with the KG7 you're stuck to 1.85 max without a volt mod. I'm hoping to do the mod to mine, though I'll probably have to upgrade my soldering iron to do it.

[Valid]

There are also AYHJA-K's out there. I know - I had one before I killed it. Heh! At any rate, my new week 25 AYHJA-Y runs at 1.61ghz. However, it's at ~2.02v. My 5v rail sags to 4.76 when I'm doing the BurnP6. The other night, it ran for hours on end, but lately, it's been crashing 10 minutes into it. Higher temps out, and the 5v line appears to sag more dramatically and quicker. I think I'm going to pick up an Antec 400W (I currently have the stock 300W that came with my Fong Kai). I've got the CPU at ~2.02V and the DDR RAM at 2.7 .

[Amedeo602]

I've got an AYHJA K.

With crappy air cooling (going to water soon...if i can get over my phobia) I can post at 1600.

[Rob Cork]

I'm hearing a lot of 'bad' things about these AYHJA cpus now - that is, if 'only' getting to 1500-1600MHz is bad :rolleyes:

Guess I got a bit lucky - mine wouldn't even run the first test in 3dmark2001 without crashing at 1600 with anything less than 1.85V. That was yesterday - today I've been running at 1600 with just 1.8V, doing SETI and a bit of FlasKmpeg encoding - no problems. Looks pretty stable. I'm hoping for 1700 eventually, though it may take a volt mod to get there.

mine ayhja y (week 28) tops out at 1.54ghz:( The temp is then under 45c so the temp should not be the problem.

how did u get it to be stable at 1.6??? On mine i will get a bluescreen after a few sec in winblows even with 1.85v which i finally managed to get.

[Hoot]

Just so we're all "Singing on the same sheet", getting through POST in not all it takes to feel secure about a successful overclock. You need to get through loading the OS and then running some CPU extreme exercising program, like F@H, Prime95, 3D Mark, etc. If it's still working after that, then you have a stable overclock. I can post at 1.6Ghz, but not make it all the way into Windows, so my system is not stable at 1.6Ghz.

Hoot

[Amedeo602]

It's like Hoot said...I didn't get it stable or anything. I didn't even change the voltage...i just wanted to see how high it would post with air and default voltage and 1600 happened to be the magical number

[fuzzba11]

Anyone here have a AYHJA Y 1000? If so, how high have you managed to push it and at what voltages? I'm getting mine tomorrow from overclockerz store...gonna run it at 1400, minimum, probably try go at least 1700 later...will a CAK38(air cooling) be able to handle it??

The CAK should be able to handle 1400, but I really doubt it will get you much above 1600.
Have you remembered to get some AS2?

Yep!
(see sig below):D

[chaosdriven]

I purchased mine here:

http://www.theoverclockerzstore.com/OCZstore.cgi?user_action=detail&catalogno=CPT-1.0AYHJA-Y

I think that there may be a bit more in the chip, but I am limited by my current cooling setup; if I notch up the voltage my temps hit the 50's and the system locks.

Waiting on that 235cfm Rotron fan model JQ12B4.....:D

Mine will only boot to windows@1605 on a warm boot....
Fastest cold boot speed about 1520....

[pvanosta]

I immediately got my AYHJA-Y 1.4 stable at 1.6 (12x133) with air cooling (a Step Thermodynamics cooler/fan I had left over from my previous CPU purchase).
From what I read here, that's not a bad result.
My problem is that, on my Iwill KA266 raid MoBo, I cannot differentiate between fsb to the cpu and system and fsb to the ram.
So: while my cpu and system look like they might want to go higher, my pc2400 ddr ram, which is running at very fast settings, won't go over 133 fsb at these settings.
So: I could bump up the fsb, but I'd pay a price in memory throughput. So I guess I'm stuck at 1600 MHz until I switch to a different MoBo

My system:
ayhja-y tbird 1.4 at 1.6 (12x133, 1.8v)
256 MB pc2400 ddr ram, cas 2

I'm debating upping my vcore even further and seeing how far I can get - kinda just as an experiment. I ran my duron at 2.32V for about 5 or 6 months, with load temps of about 52C (as reported by Asus Probe - so probably in reality closer to 42-45C). So I'm sure the chip can survive it. At the moment I'm running 1680 with 2.11V, as my sig says. My load temps are generally about 21C above ambient, and the highest ambient ever really gets is 24C - so the max temp in my sig of 45C really is the maximum temp I've seen. Hmmm - to go to 2.2 or not to go to 2.2? That is the question :)

With Athlon's so cheap, I say go for it. I can't believe you got a Duron to run at 2.32V. I am not that brave. I get worried bumping the core .1V, and you're going .7V! (Duron's are 1.6V default, right?)

Have you tried memory benchmarking it with SiSandra?
Your score might prove to be substantially higher with a higher FSB, despite more conservative memory settings.....
