Would it be better to run the low voltage kit with CAS9 timings, or the 2133 kit with CAS11, or something in between? I know this 2133 kit will do 2000mhz at 9-10-9-30 1T with Ivy Bridge but I don't know how good this IMC is, would that be my best bet?

If your benching: Higher ram speed

If your looking for usable performance: 1600 @ CAS 8 is a sweet spot. (push the voltage on thos 1600 chips)

Ok, thanks. I don't care about benching I just want the best for daily use. I'll see what I can get out of the low voltage kit at 1.5v JEDEC spec instead of the XMP profile 1.35v, its Patriot not Samsung so who knows what it will do.

2) There was never a problem with the IMC. L3 cache speed was bound to the Northbridge speed; faster northbridge = faster Cache.

3) The only reason the NB felt "slow" was that the NB speed should be 1.5x the RAM speed in that design. 1333 RAM should have a 2000 NB (and hey, 1333 was the supported speed too). In their own guide for the chip, they recommended 2400 for 1600 RAM as well. It's also a large heat increase to clock up the NB, something they would like to avoid. Enthusiasts who would have put in faster ram would likely be overclocking anyway, so it was a workable solution.

So... ya. Understand what you're talking about before you call AMD stupid next time.

Good points Kyad. I should not have been so "general" about what I was posting. But nowhere did I state that I was smarter than AMD, and nowhere did I state that AMD was stupid.
I was merely making an observation, and asked if anyone could do a general verification by testing it. I actually tried it out because the person I sold this pc to was a family member.

By reducing the CPU/NB speed to 1600Mhz @ 1.05v and running my system Ram at 1600Mhz, I was able to reduce system temps by 6 Celsius and run Prime stable at 1.325v @ 4.5Ghz as opposed to 1.338v. (Core 8 no longer drops out at the stock voltage) ***No idea if this would be typical results, as every CPU is a little different.
Reducing the system Ram to 1333Mhz and further lowering the CPU/NB to 1400Mhz didn't allow any lower CPU voltage, but it did seem like the system would hang slightly.

It would take a lot more testing to know if there is a performance reduction with the reduced CPU/NB Speeds - which I don't have time to perform.

At that point your just bottlenecking the the cache to processor.

This is pretty interesting, I would be willing to do some testing with it as well if you have a list of things you want run.

Generally, "leave it alone". The extra voltage, heat, and instability are not worth the almost unseen benefit of making the northbridge faster. Since the NB is no longer bound to cache, it's not a simple "make it faster" deal like with the Ph IIs.

Someone in the thread said the NB should be at, or above, the speed of the RAM at all times, which makes sense since the IMC is part of the CPU/NB, so we'll go with that.

No, because there is no TIM under the IHS, it's soldered directly. Attempting to remove it will break the chip.

On the topic here,

I know when I keep my PHII at a constant clock but only change the ram speed I see a large increase in heat output. I suppose this is the same effect as keeping the processor at the same voltage but clocking it higher... it increases heat.

Simply asking the unit to "do more work". I cant get a stable speed @ or above 1866 ram @ 3ghz NB... but I can decrease the NB to about 2600mhz and increase the ram speed... but then it's a trade off and I'm loosing NB performance (caches are clocked lower).

I can only assume the same principle exists with Bulldozer / piledriver.

And further more, the changes in Pildriver show up in the L2 cache performance:
Quote:
AnandTech - AMD Launches Opteron 6300 series with "Piledriver" cores

The L2 cache latency and bandwidth has not changed, but AMD did quite a few optimizations. From AMD engineering:

"While the total bandwidth available between the L2 and the rest of the core did not change from Bulldozer to Piledriver, the existing bandwidth is now used more effectively. Some unnecessary instruction decode hint data writes to the L2 that were present in Bulldozer have been removed in Piledriver. Also, some misses sent to the L2 that would get canceled in Bulldozer are prevented from being sent to the L2 at all in Piledriver. This allows the L2’s existing resources to be applied toward more useful work.”

This Means that cache operations misses in L1 that would have normally been set to L2 (which created a lot of bulldozers cache latency issues) are now not allowed to take the cache cycles away from the pipeline. Requiring instead a new start cycle. This apparently is faster than than the cache continuing the search than just starting the operation again. I assume because of the the longer cycle length of the pipeline in AMD's new CMT cores. (and is also why you see the L2 cache performance differences in vishera vs. zambezi... look at the L2 Read performance numbers in Aida64 memory benchmark)

This is more of a instant performance "work around" than it is a design improvement. I don't know if this can even be solved until the 28nm fab due to the need for lower latency caches while maintaining the high clock necessary (which increases the bandwidth) to keep the cores fed.

AMD pretty much has the beginnings of a great pipeline but cant keep it fed do to cache restraints that are ultimately restricted by the fab process. Add on top of that the small associative L1 cache Piledriver is coping with, and you have the ultimate inability to get the correct information on the fly to the pipeline.

This is why Piledriver is great at parallel tasks right now, but falls short in random IO (or IMC) operations. Its really all about the cache, prefetch, branch misprediction cycle penalty, and lack of decode per core.
Quote:
The Bulldozer Aftermath: Delving Even Deeper


The Real Shortcomings: Branch Misprediction Penalty and Instruction Cache Hit Rate

Bulldozer is a deeply pipelined CPU, just like Sandy Bridge, but the latter has a µop cache that can cut the fetching and decoding cycles out of the branch misprediction penalty. The lower than expected performance in SAP and SQL Server, plus the fact that the worst performing subbenches in SPEC CPU2006 int are the ones with hard to predict branches, all points to there being a serious problem with branch misprediction.

Our Code Analyst profiling shows that AMD engineers did a good job on the branch prediction unit: the BPU definitely predicts better than the previous AMD designs. The problem is that Bulldozer cannot hide its long misprediction penalty, which Intel does manage with Sandy Bridge. That also explains why AMD states that branch prediction improvements in "Piledriver" ("Trinity") are only modest (1% performance improvements). As branch predictors get more advanced, a few tweaks here and there cannot do much.

It will be interesting to see if AMD will adopt a µop cache in the near future, as it would lower the branch prediction penalty, save power, and lower the pressure on the decoding part. It looks like a perfect match for this architecture.

Another significant problem is that the L1 instruction cache does not seem to cope well with 2-threads. We have measured significantly higher miss rates once we run two threads on the 2-way 64KB L1 instruction cache. It looks like the associativity of that cache is simply too low. There is a reason why Intel has an 8-way associative cache to run two threads.

Good way to sum it up, although you have the cache order reversed. RAM -> L3 -> L2 -> L1 -> Core cache misses would be in a higher value.

Someone posted an overclocking guide from AMD and in it is said to run NB at or above the RAM speed.

For attention of ComputerRestore biggrin.gif

I ran a few tests on your idea of reduced NB + Voltage etc and am posting results here for your information.

I tested using IBT ( AVX Version ) and Cinebench 64Bit CPU Multithreaded test, under the following conditions >


Kingston 1600Mhz Ram @ 1.65v 9-9-9-27 <><><><><> CPU @ 4.50Ghz 1.325v ( 23x200 ) <><><><><> H100 Fans @ Low Speed


First Test result with CPU/NB @ 2200Mhz ~ 1.18v ( Auto by default on my mobo )

IBT x 10 Runs = Average 81 GFlops >>> Temps @ Load 40-44c

Cinebench Multithreaded = 7.64 pts >>> Temps @ Load 43c



Second Test result with CPU/NB @ 1600Mhz ~ 1.05 ( Manual adjust )

IBT x 10 Runs = Average 82.6 GFlops >>> Temps @ Load 35-39c

Cinebench Multithreaded = 7.58 pts >>> Tempe @ Load 42c


I hope this information proves helpful to you smile.gif
