1045T OC, Farewell to K8

I gave my 1090T to a beloved friend who wanted it and haven't been paying attention to the world of CPU for some time. The other day I stopped at the Micro Center and learned that AMD stopped making Thubans. (promoting Bulldozer instead, I suppose :biggrin: ) They only had 1045Ts in stock, and a quick checking on-line also showed these chips are disappearing.

Realizing that the chance of getting a 6+ core CPU for a decent price in the near future is slim (Bulldozer doesn't count), I picked up the 1045T for $99. (Believe it or not they give you a crappy $50 board for free with that)

Pleasant result.

Six 45nm cores @4.0+ GHz aren't bad at all. Strong memory controller (for an AMD chip) as well. This chip will be the last legacy of the venerable K8 for me.
 
Wow, 4Ghz, at under 1.4v. Nice.

My 1045T, I couldn't get stable at 3.8, so I didn't even try 4.0. I only went up to 1.38v.

Currently sitting at 3.51Ghz, 1.325v (stock, I think).

Edit: I don't see temps listed. What cooling are you using, and what temps do you see?
 
well there's also a 960T which I heard has a 30% chance of turning into an X6.

but I can't argue w/ this price $100 for a cpu+mb.
 
Wish there was a Microcentre near me here in the UK. Even with VAT $100 is only £77 and there's no way you'd get a mobo + CPU for that here. :-(

100 bucks for 6 cores @4ghz? really hard to argue with that, especially if you are doing a lot of multitasking.

Six real cores unlike the FX-6000 series, mind you.

Not bad if you don't care for the power consumption and want decent MT performance.
 
Well, $100 with motherboard is about what they are worth. You can go on ebay and get an i3-540 and H55 motherboard for not much more, and overclock that to 4GHz too. And I'd rather have a 4GHz i3 any day. It might not transcode as fast but I dont sit around waiting for anything which taxes more than 2 cores. The single and dual threaded performance is just too good to pass up.

Temps are impossible to read via software. (Would you believe 16C, 18C,.. etc.) BIOS reading gives more realistic measure (mid 30C) but they're not load temps. I'm using Scythe Infinity push/pull. 3.90 GHz (13x300) is stable with 1.35V and without a second fan. I might settle there instead of raising extra 0.05V for mere 150 MHz. But as you might know the real deal here is the 3.0 GHz CPU-NB, syncronized with 300HTT/DDR3-1600. I was very happy with that since that really matters for Thubans.

I have a 2500K @4.80 GHz for that purpose. Zero interest in i3, thank you.

I just seen that MC had them $99. Can't beat that price.

When I gave away my 1090T I thought Thubans (esp. 1090T/1100T) would come down to bargain bin in the future. But instead they're being discontinued apparently. It was an impulse turned out to be a satisfaction, which is usually a rare feat achieved by me.

3Ghz CPU-NB, wow that is mighty impressive that must fly. I remember how much the minimum FPSes improved in WoW when I cranked the CPU-NB from 2ghz to 2.6ghz, can't imagine what 3 would be like!

I'll give you a few weeks before you start eyeing the intel line.. gaming performance just isn't there on the AMD

It looks like it hasn't even been a few weeks since you joined this forum? (Your post gives me a hint of your demographic nature, though.)

You missed out the (many) golden ages of this hobby, my friend. There will not be much fun left in overclocking or any user tweaking in this field very soon. Everything will be either be ready-made, or your effort will be reduced to mere assembly. (And I'll gladly pass such chores) Hope you enjoy whatever is left under your control for now. Time is running out. 🙂

Ivy Brdige has injected plenty of gold into todays age. Have you seen the lengths some people are going through to keep temps in check? 😉

what settings are you using to get it to 4ghz? What HT, NB, etc
Click to expand...

These are the exact settings (ASUS 89GTD-USB3). Memory is Corsair XMS 2GBx4, set to 7-8-7-1T and everything else auto.

You're quite right about that. Check the CPU-NB scaling on SC2 here -> http://www.anandtech.com/show/3877/...investigation-of-thuban-performance-scaling/7

I could go on and provide empirical data between my setups (2500K and this thuban @4.0 GHz Core / 3.0 GHz CPU-NB) but I'd refrain from doing so for fear of ruining this thread. But IMO it's ultimately AMD's fault that it couldn't provide the best possible performance of its own products. Especially ironic since AMD used to attack Intel's (admittedly lackluster) FSB subsystem. With K10, the CPU-NB essentially was AMD's version of FSB. (From the sync issue with HT to the abysmal thermals, and many more) Reviewers won't waste time optimizing AMD platform when end-users are not likely do such, and Intel platform generally provides much better out-of-the-box performance. "Black Edition" SKUs were also arguably a double-edged sword for PR because many reviewers/users simply raised the multipliers and called it a day. For sure, it's always nice to have unlocked multiplier. But when your L3/memory controller run async with the execution cores, it becomes complicated to find the balance and the benefits of faster execution cores are often wasted. (But I'm not complaining. If everyone were so savvy I wouldn't have gotten this 1045T for cheap!)

Edit: You mean, cooling? I suppose some folks (with slightly masochistic characteristics) will enjoy it. You're probably right on that. But you aren't likely to see anyone devoting (or being able to devote) their time for quests such as these:

Or even something like this.

I do multitask somewhat. Well, the PC does. (My brain is usually the bottleneck in my daily computing 🙂 ) CPU 4/5 are reserved for VMs for serving and some "shadowy" computing. CPU 2/3 are for encoding and/or browsing. CPU 0/1 for work and games. I use Windows Task Manager to set processor affinities manually.

Haha, couldn't agree with you more there 😎

My Thubans require more voltage to hit 4.0. You've got a really nice chip. I suppose, those later manufactured pieces of silicon had matured greatly.

If you are running the GA-78LMT-SP2 rev 4.0 board in that combo, be careful. I've killed two of them with slight overclocks. The VRM's just can't handle it. Was running stock voltage. Last kill started a fire that fortunately went out quickly.

I picked that one indeed. (There were 3 choices of $50 boards to pick, haha) I haven't opened it yet and I think I will list it on eBay and see if it sells. Thank you for the advice. Yes, the board looks weak and it doesn't surprise me that it doesn't get along with overclocking.
 
It seems that you got a golden chip.
The main frequency is very nice at that voltage, but the NB frequency is almost unheard-of. :thumbsup:
